Bitcoin Risk (Long Position). Through its long position in bitcoin, the Fund is subject to the risk that bitcoin’s value decreases. If the value of bitcoin decreases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. Therefore, as a result of the Fund’s exposure to the value of bitcoin, the Fund may also be subject to the following risks:

 

The risks associated with bitcoin include the possibility of fraud, theft, market manipulation, and security breaches in trading platforms. A small group of large bitcoin holders, known as “whales,” can significantly influence bitcoin’s price and may have the ability to manipulate the price. The largely unregulated nature of bitcoin and its trading venues heightens risks of fraudulent activities and market manipulation, which could affect bitcoin’s price. For example, if a group of miners gains control over a majority of the bitcoin network, they could manipulate transactions to their advantage. Historical instances have seen bitcoin trading venues shut down due to fraud or security breaches, often leaving investors without recourse and facing significant losses.

 

Updates to bitcoin’s software, proposed by developers, can lead to the creation of new digital assets, or “forks,” if not broadly adopted. This can impact bitcoin’s demand and the Fund’s performance. The extreme volatility of bitcoin’s market price can result in shareholder losses. Furthermore, the operation of bitcoin trading platforms may be disrupted or cease altogether due to various issues, further affecting bitcoin’s price and the Fund’s investments.

 

The value of bitcoin has historically been subject to significant speculation, making trading and investing in bitcoin reliant on market sentiment rather than traditional fundamental analysis.

 

Bitcoin’s price can be influenced by events unrelated to its security or utility, including instability in other speculative areas of the crypto/blockchain space, potentially leading to substantial declines in its value.

 

Risks associated with crypto asset trading platforms include fragmentation, regulatory non-compliance, and the possibility of enforcement actions by regulatory authorities, which could impact the valuation of bitcoin-linked derivatives held by the Fund.

 

The security of the Bitcoin Blockchain may be compromised if a single miner or group controls more than 50% of the network’s hashing power, where hashing power refers to the computational capacity used to validate and secure transactions on the blockchain.

 

Proposed changes to the bitcoin protocol may not be universally adopted, leading to the creation of competing blockchains (forks) with different assets and participants, exemplified by past forks like Bitcoin Cash and Bitcoin SV.

 

The Bitcoin Blockchain protocol may contain vulnerabilities that attackers could exploit to disrupt its operation, potentially compromising the security and reliability of the network.

 

Emerging alternative public blockchains, particularly those emphasizing privacy through technologies like zero-knowledge cryptography, pose risks and challenges to the dominance of the Bitcoin Blockchain as a payment system.

 

Common impediments to adopting the Bitcoin Blockchain as a payment network include slow transaction processing, variability in transaction fees, and the volatility of bitcoin’s price, which may deter widespread adoption by businesses and consumers.

 

The development and use of “Layer II solutions” are critical for the scalability and functionality of the Bitcoin Blockchain, but they also introduce risks such as off-chain transaction execution, which could affect transparency and security. Layer II solutions are off-chain protocols that improve scalability and reduce transaction costs by processing transactions outside the main blockchain network.

 

Adoption and use of other blockchains supporting advanced applications like smart contracts present challenges to the dominance of the Bitcoin Blockchain, potentially impacting its long-term relevance and utility in the evolving landscape of blockchain technology.

 

Defiance Bitcoin vs Ether ETF | Ether Appreciation Risk (Short Position) [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Ether Appreciation Risk (Short Position). By virtue of the Fund’s inverse exposure to changes in the value of ether, the Fund is subject to the risk that ether’s value increases. If the value of ether increases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. Ether is relatively new and the market for ether is subject to rapid price swings, changes and uncertainty. Rapid increases in the value of ether may result in substantial losses for the Fund. In addition, the further development of the Ethereum Network and the broad acceptance and use of ether would likely result in an increase in the value of ether, which could result in significant losses for the Fund.

 

In addition, as a result of the Fund’s short exposure to the value of ether, the Fund may also be subject to the following risks:

 

Defiance Bitcoin vs Ether ETF | Growing Adoption and Use Cases [Member]

Risk [Text Block]

Growing Adoption and Use Cases: Ethereum is a blockchain platform that enables the creation of decentralized applications (DApps) and smart contracts. If the adoption of Ethereum continues to grow, which could be driven by developers building innovative projects and businesses utilizing its platform, the demand for ether (the native crypto asset of Ethereum) would likely increase. Such an increased demand could cause the price of ether to rise, which would negatively impact the Fund’s performance.

Risk [Text Block]

DeFi (Decentralized Finance) Boom: Ethereum has become the primary platform for the decentralized finance (DeFi) applications, which may continue strong growth. These applications enable financial services such as lending, borrowing, trading, and yield farming without intermediaries. If the DeFi ecosystem expands and more value is locked into DeFi protocols, the demand for ether could increase causing the price of ether to rise, which would negatively impact the Fund’s performance.

 

Defiance Bitcoin vs Ether ETF | NFT (Non-Fungible Token) Craze [Member]  
Prospectus [Line Items]  
Risk [Text Block]

NFT (Non-Fungible Token) Craze: Non-fungible tokens (NFTs) have gained significant attention, especially in the art and collectibles space. Ethereum is the primary blockchain used for creating and trading NFTs. If NFTs gain popularity, the demand for ether could increase causing the price of ether to rise, which would negatively impact the Fund’s performance.

 

Defiance Bitcoin vs Ether ETF | Upgrades and Improvements [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Upgrades and Improvements: Ethereum is undergoing upgrades to improve scalability, security, and efficiency. The transition to Ethereum 2.0, which includes the shift to a proof-of-stake consensus mechanism and the implementation of sharding, is expected to enhance the network’s capabilities and reduce transaction fees. Positive developments and progress on these upgrades may instill confidence in the Ethereum ecosystem, attracting more investors. In that case, the price of ether could rise, which would negatively impact the Fund’s performance.

 

Defiance Bitcoin vs Ether ETF | Institutional Adoption [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Institutional Adoption: Institutional investors and corporations are increasingly showing interest in crypto assets as an asset class. With the emergence of regulated investment vehicles such as Ethereum-based exchange-traded funds (ETFs) and the growing acceptance of crypto assets by traditional financial institutions, institutional adoption of Ethereum could accelerate, leading to increased demand and price appreciation. Such adoption could cause the price of ether to rise, which would negatively impact the Fund’s performance.

 

Defiance Bitcoin vs Ether ETF | Macroeconomic Factors [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Macroeconomic Factors: Economic uncertainty, inflation concerns, and currency devaluation in traditional financial markets can drive investors towards alternative assets like crypto assets, including ether, as a hedge against economic instability. Additionally, monetary policies implemented by central banks, such as quantitative easing, can contribute to the devaluation of fiat currencies, making crypto assets more attractive as store of value assets. Such macroeconomic factors could cause the price of ether to rise, which would negatively impact the Fund’s performance.

 

Defiance Bitcoin vs Ether ETF | Technological Innovation [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Technological Innovation: Ongoing technological advancements and developments within the Ethereum ecosystem, such as layer 2 scaling solutions, interoperability with other blockchains, and improvements in security and usability, have the potential to enhance the utility and attractiveness of ether, driving increased demand and price appreciation, which would negatively impact the Fund’s performance.

 

Defiance Bitcoin vs Ether ETF | Digital Assets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Digital Assets Risk. Digital assets like bitcoin and ether, designed as mediums of exchange, are still an emerging asset class and are not presently widely used as such. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated or possibly operating out of compliance with regulations, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility.

 

The digital asset market has experienced considerable volatility, leading to market disruptions and erosion of confidence among market participants. This instability and the resultant negative publicity could adversely affect the Fund’s reputation and trading prices. Ongoing market turbulence could significantly impact the value of the Fund’s share.

 

Blockchain technology, which underpins bitcoin and other digital assets, is relatively new, and many of its applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology.

 

Defiance Bitcoin vs Ether ETF | Leveraging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leveraging Risk. The Fund’s use of leverage amplifies both potential gains and potential losses, which can result in significant volatility and higher risk for investors. Specifically, bitcoin, the Fund’s leveraged long position (“Long Position”) and, ether, the leveraged short position (“Short Position”), expose the Fund to heightened risk if the Long Position performs poorly while the Short Position performs well.

 

If the value of the Long Position declines, the Fund’s leveraged exposure could result in losses that are magnified by the leverage factor, potentially exceeding the losses that would occur in an unleveraged position. For example, if the Fund’s Long Position is at +200% of net assets, a 10% decline in the value of the Long Position could translate into a 20% loss for the Fund’s net asset value attributable to that position.

 

Conversely, if the value of the Short Position increases, the Fund’s leveraged short exposure could also lead to magnified losses. If the Short Position is at -200% of net assets, a 10% rise in the value of the Short Position could result in a 20% loss for the Fund’s net asset value attributable to that position.

 

In scenarios where the Long Position underperforms and the Short Position outperforms simultaneously, the Fund could experience compounded losses from both positions. This dual risk could lead to significant declines in the Fund’s net asset value, particularly because the losses from one position may not be sufficiently offset by gains in the other, especially when leverage is applied.

 

Investors should be aware that the use of leverage increases the Fund’s sensitivity to market movements and can lead to substantial losses in a relatively short period. The Adviser’s active management and rebalancing efforts, while designed to manage exposure levels, cannot eliminate the inherent risks associated with leveraged positions. As such, the Fund may experience periods of extreme volatility, and the potential for loss is significant, particularly if market conditions do not align with the Fund’s investment strategy.

 

Defiance Bitcoin vs Ether ETF | Opposing Performance Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Opposing Performance Risks: The Fund’s strategy of holding a long position in one asset and a short position in another asset involves significant risks. From time to time, both positions may experience losses (i.e., the value of the asset held long declines, while the value of the asset held short increases). Such outcomes could occur due to a range of factors, including adverse market conditions, unexpected developments, or macroeconomic events that create opposing price movements in the paired securities.

 

Defiance Bitcoin vs Ether ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s derivative investments carry risks such as an imperfect match between the derivative’s performance and its underlying asset, and the potential for loss of principal, which can exceed the initial investment. Additionally, there are risks related to the possible default of the transaction’s counterparty and the illiquidity of derivatives, making them hard to sell or trade. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding. The derivatives used by the Fund will give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss. Certain of the Fund’s transactions in derivatives could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

 

Defiance Bitcoin vs Ether ETF | Futures [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Futures. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract.

 

Defiance Bitcoin vs Ether ETF | Swaps [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Swaps. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. The Fund’s swap agreements are subject to mandatory clearing, which means they must be transacted through a futures commission merchant and cleared through a clearinghouse that serves as a central counterparty. Swaps involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a swap due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the swap in a bankruptcy or other reorganization proceeding. This risk is heightened with respect to OTC instruments, such as the swaps in which the Fund will invest, and may be greater during volatile market conditions. Other risks include the inability to close out a position because the trading market becomes illiquid (particularly in the OTC markets) or the availability of counterparties becomes limited for a period of time. Certain of the Fund’s transactions in swaps could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

 

Defiance Bitcoin vs Ether ETF | Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Options. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the underlying asset. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. If the Fund sells an option, it sells to another person the right to buy from or sell to the Fund (i.e., “call” or “put,” respectively) a specific amount of the underlying asset at an agreed-upon price, typically in exchange for a premium received by the Fund. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well-conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile, and the use of options can lower total returns.

 

Defiance Bitcoin vs Ether ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.

 

Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

 

Defiance Bitcoin vs Ether ETF | Short Sales Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Short Sales Risk. In connection with a short sale of a security or other instrument, the Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases, the Fund will experience a loss, which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase.

 

Defiance Bitcoin vs Ether ETF | Underlying Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Underlying Fund Risk. The Fund’s investment strategy, involving indirect exposure to bitcoin and ether through one or more Underlying Funds, is subject to the risks associated with bitcoin and ether. Shareholders in the Fund bear both their proportionate share of expenses in the Fund and, indirectly, the expenses of the Underlying Funds.

 

Defiance Bitcoin vs Ether ETF | Underlying Bitcoin Funds - Long Exposure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Underlying Bitcoin Funds - Long Exposure Risks: Investing in an Underlying Fund that focuses on bitcoin, either through direct holdings or indirectly via derivatives like futures contracts and swaps, carries significant risks. These risks include high market volatility, which can be influenced by technological advancements, regulatory changes, and broader economic factors. When trading derivatives, liquidity risks and counterparty risks are substantial. Managing futures contracts can be complex and may affect the performance of an Underlying Fund. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Additionally, each Underlying Fund, and consequently the Fund, is dependent on blockchain technology, which brings technological and cybersecurity risks, along with custodial challenges for securely storing digital assets. The constantly evolving regulatory and legal landscape presents continuous compliance and valuation difficulties. Risks related to market concentration and network issues in the digital asset sector further add complexity. Moreover, operational intricacies in managing digital assets and potential market volatility can lead to losses for an Underlying Fund. These risks are magnified with respect to Underlying Funds that provide leveraged exposure to bitcoin, which could lead to amplified losses for the Fund.

     

Defiance Bitcoin vs Ether ETF | Underlying Ether Funds - Short Exposure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Underlying Ether Funds - Short Exposure Risks: The Fund seeks short exposure to Underlying Funds that focuses on ether (Underlying Ether Funds) directly or through derivatives such as futures contracts and swaps. If the value of an Underlying Ether Fund increases, the Fund will incur a loss, which could be substantial. Factors such as high market volatility, technological advancements, regulatory developments, and market concentration in the digital asset sector may cause the value of Underlying Ether Funds to rise, negatively impacting the Fund’s performance. Underlying Ether Funds’ use of derivatives subjects them to liquidity, counterparty, leverage, and futures risks, which can amplify price movements to the detriment of the Fund’s short position. Additionally, reliance on blockchain technology introduces technological, cybersecurity, and custodial risks that can cause further price increases. These risks are magnified with respect to Underlying Funds that provide leveraged exposure to ether, which could lead to amplified losses for the Fund.

     

Defiance Bitcoin vs Ether ETF | Potentially No 1940 Act Protections [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Potentially No 1940 Act Protections. It is expected that one or more Underlying Funds will not be registered as an investment company subject to the 1940 Act. In addition, Underlying Funds that invest directly in bitcoin or ether are not subject to the 1940 Act. Accordingly, investors in such an Underlying Fund would not have the protections expressly provided by that statute, including: provisions preventing Underlying Fund insiders from managing an Underlying Fund to their benefit and to the detriment of shareholders; provisions preventing an Underlying Fund from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing Underlying Fund earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in an Underlying Fund’s character without the consent of shareholders. The Fund’s investments are subject to loss as a result of these risks.

 

Defiance Bitcoin vs Ether ETF | Cayman Subsidiary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cayman Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which the Fund is subject, such as tax risks, commodity related risks, and market and data risks.

 

Defiance Bitcoin vs Ether ETF | Commodity-Linked Derivatives Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Commodity-Linked Derivatives Tax Risk.  The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations, or other legally binding authority. As a RIC, the Fund must derive at least 90% of its gross income each taxable year from certain qualifying sources of income under the Code. If, as a result of any adverse future legislation, U.S. Treasury regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”), the income of the Fund from certain commodity-linked derivatives, including income from the Fund’s investments in the Subsidiary, were treated as non-qualifying income, the Fund may fail to qualify as RIC and/or be subject to federal income tax at the Fund level. The uncertainty surrounding the treatment of certain derivative instruments under the qualification tests for a RIC may limit the Fund’s use of such derivative instruments.

 

Defiance Bitcoin vs Ether ETF | Commodity Pool Regulatory Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Commodity Pool Regulatory Risk.  The Fund’s strategy will cause it to be deemed a commodity pool, thereby subjecting the Fund to regulation under the Commodities Exchange Act of 1936, as amended (the “CEA”) and CFTC rules. The Adviser is registered as a commodity pool operator (“CPO”) and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO imposes additional compliance obligations on the Adviser and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s registration as a CPO is not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.

 

Defiance Bitcoin vs Ether ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund intends to treat any income received by the Subsidiary as “qualifying income” under the provisions of the Code applicable to RICs. The IRS has issued numerous private letter rulings (“PLRs”) provided to third parties not associated with the Fund or its affiliates (which only those parties may rely on as precedent) concluding that similar arrangements resulted in qualifying income. Many of such PLRs have now been revoked by the IRS. In March of 2019, the IRS published Regulations that concluded that income from a corporation similar to the Subsidiary would be qualifying income. Although the Regulations do not require distributions from the Subsidiary, the Fund intends to cause the Subsidiary to make distributions that would allow the Fund to make timely distributions to its shareholders and to meet the requirement that the Subsidiary have a value not in excess of 25% of the Fund’s value at the close of a quarter. The Fund generally will be required to include in its own taxable income the income of the Subsidiary for a tax year, regardless of whether the Fund receives a distribution of the Subsidiary’s income in that tax year, and this income would nevertheless be subject to the distribution requirement for qualification as a regulated investment company and would be taken into account for purposes of the 4% excise tax.

 

If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objective and strategies. In the event that the Fund fails to qualify as a RIC, the Fund will promptly notify shareholders of the implications of that failure.

 

Defiance Bitcoin vs Ether ETF | Concentration Risk [Member]

Concentration Risk. The Fund’s investments will be concentrated in bitcoin and ether, which are crypto assets. The value of the Fund’s shares may rise and fall more than the value of shares that invest in securities of companies in a broad range of industries.

 

Defiance Bitcoin vs Ether ETF | Economic and Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.  The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Defiance Bitcoin vs Ether ETF | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

     

Defiance Bitcoin vs Ether ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

     

Defiance Bitcoin vs Ether ETF | Costs of Buying or Selling Shares [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

     

Defiance Bitcoin vs Ether ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

     

Defiance Bitcoin vs Ether ETF | Trading [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to just two underlying stocks as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. In the event of an unscheduled market close for derivatives that reference a single stock, such as either of the underlying company’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the relevant derivatives. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Risk [Text Block]

High Portfolio Turnover Risk. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds and depositary accounts. The Fund will incur expenses when investment in money market instruments, which will reduce performance. Money market instruments may lose money.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

Defiance Bitcoin vs Ether ETF | Reverse Repurchase Agreement Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Reverse Repurchase Agreement Risk. Similar to borrowing, reverse repurchase agreements provide the Fund with cash for investment purposes, which creates leverage and subjects the Fund to the risks of leverage. Reverse repurchase agreements also involve the risk that the other party may fail to return the securities in a timely manner or at all. The Fund could lose money if it is unable to recover the securities and/or if the value of collateral held by the Fund, including the value of the investments made with cash collateral, is less than the value of securities.

Prospectus [Line Items]  
Risk [Text Block]

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Institutional Adoption: Institutional investors and corporations are increasingly showing interest in crypto assets as an asset class. With the emergence of regulated investment vehicles such as bitcoin-based exchange-traded funds (ETFs) and the growing acceptance of crypto assets by traditional financial institutions, institutional adoption of bitcoin could accelerate, leading to increased demand and price appreciation. Such adoption could cause the price of bitcoin to rise, which would negatively impact the Fund’s performance.

Macroeconomic Factors: Economic uncertainty, inflation concerns, and currency devaluation in traditional financial markets can drive investors towards alternative assets like crypto assets, including bitcoin, as a hedge against economic instability. Additionally, monetary policies implemented by central banks, such as quantitative easing, can contribute to the devaluation of fiat currencies, making crypto assets more attractive as store of value assets. Such macroeconomic factors could cause the price of bitcoin to rise, which would negatively impact the Fund’s performance.

Defiance Ether vs Bitcoin ETF | Digital Assets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Digital Assets Risk. Digital assets like ether and bitcoin, designed as mediums of exchange, are still an emerging asset class and are not presently widely used as such. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated or possibly operating out of compliance with regulations, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility.

 

The digital asset market has experienced considerable volatility, leading to market disruptions and erosion of confidence among market participants. This instability and the resultant negative publicity could adversely affect the Fund’s reputation and trading prices. Ongoing market turbulence could significantly impact the value of the Fund’s share.

 

Blockchain technology, which underpins bitcoin and other digital assets, is relatively new, and many of its applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology.

 

Defiance Ether vs Bitcoin ETF | Leveraging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leveraging Risk. The Fund’s use of leverage amplifies both potential gains and potential losses, which can result in significant volatility and higher risk for investors. Specifically, ether, the Fund’s leveraged long position (“Long Position”) and, bitcoin, the leveraged short position (“Short Position”), expose the Fund to heightened risk if the Long Position performs poorly while the Short Position performs well.

 

If the value of the Long Position declines, the Fund’s leveraged exposure could result in losses that are magnified by the leverage factor, potentially exceeding the losses that would occur in an unleveraged position. For example, if the Fund’s Long Position is at +200% of net assets, a 10% decline in the value of the Long Position could translate into a 20% loss for the Fund’s net asset value attributable to that position.

 

Conversely, if the value of the Short Position increases, the Fund’s leveraged short exposure could also lead to magnified losses. If the Short Position is at -200% of net assets, a 10% rise in the value of the Short Position could result in a 20% loss for the Fund’s net asset value attributable to that position.

 

In scenarios where the Long Position underperforms and the Short Position outperforms simultaneously, the Fund could experience compounded losses from both positions. This dual risk could lead to significant declines in the Fund’s net asset value, particularly because the losses from one position may not be sufficiently offset by gains in the other, especially when leverage is applied.

 

Investors should be aware that the use of leverage increases the Fund’s sensitivity to market movements and can lead to substantial losses in a relatively short period. The Adviser’s active management and rebalancing efforts, while designed to manage exposure levels, cannot eliminate the inherent risks associated with leveraged positions. As such, the Fund may experience periods of extreme volatility, and the potential for loss is significant, particularly if market conditions do not align with the Fund’s investment strategy.

 

Defiance Ether vs Bitcoin ETF | Opposing Performance Risks [Member]

Opposing Performance Risks: The Fund’s strategy of holding a long position in one asset and a short position in another asset involves significant risks. From time to time, both positions may experience losses (i.e., the value of the asset held long declines, while the value of the asset held short increases). Such outcomes could occur due to a range of factors, including adverse market conditions, unexpected developments, or macroeconomic events that create opposing price movements in the paired securities.

 

Defiance Ether vs Bitcoin ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s derivative investments carry risks such as an imperfect match between the derivative’s performance and its underlying asset, and the potential for loss of principal, which can exceed the initial investment. Additionally, there are risks related to the possible default of the transaction’s counterparty and the illiquidity of derivatives, making them hard to sell or trade. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding. The derivatives used by the Fund will give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss. Certain of the Fund’s transactions in derivatives could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

 

Defiance Ether vs Bitcoin ETF | Futures [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Futures. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract.

 

Defiance Ether vs Bitcoin ETF | Swaps [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Swaps. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. The Fund’s swap agreements are subject to mandatory clearing, which means they must be transacted through a futures commission merchant and cleared through a clearinghouse that serves as a central counterparty. Swaps involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a swap due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the swap in a bankruptcy or other reorganization proceeding. This risk is heightened with respect to OTC instruments, such as the swaps in which the Fund will invest, and may be greater during volatile market conditions. Other risks include the inability to close out a position because the trading market becomes illiquid (particularly in the OTC markets) or the availability of counterparties becomes limited for a period of time. Certain of the Fund’s transactions in swaps could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

 

Defiance Ether vs Bitcoin ETF | Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Options. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the underlying asset. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. If the Fund sells an option, it sells to another person the right to buy from or sell to the Fund (i.e., “call” or “put,” respectively) a specific amount of the underlying asset at an agreed-upon price, typically in exchange for a premium received by the Fund. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well-conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile, and the use of options can lower total returns.

 

Defiance Ether vs Bitcoin ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.

 

Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

Short Sales Risk. In connection with a short sale of a security or other instrument, the Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases, the Fund will experience a loss, which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase.

 

Defiance Ether vs Bitcoin ETF | Underlying Fund Risk [Member]

Underlying Fund Risk. The Fund’s investment strategy, involving indirect exposure to ether and bitcoin through one or more Underlying Funds, is subject to the risks associated with ether and bitcoin. Shareholders in the Fund bear both their proportionate share of expenses in the Fund and, indirectly, the expenses of the Underlying Funds.

 

Defiance Ether vs Bitcoin ETF | Potentially No 1940 Act Protections [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Potentially No 1940 Act Protections. It is expected that one or more Underlying Funds will not be registered as an investment company subject to the 1940 Act. In addition, Underlying Funds that invest directly in ether or bitcoin are not subject to the 1940 Act. Accordingly, investors in such an Underlying Fund would not have the protections expressly provided by that statute, including: provisions preventing Underlying Fund insiders from managing an Underlying Fund to their benefit and to the detriment of shareholders; provisions preventing an Underlying Fund from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing Underlying Fund earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in an Underlying Fund’s character without the consent of shareholders. The Fund’s investments are subject to loss as a result of these risks.

 

Defiance Ether vs Bitcoin ETF | Cayman Subsidiary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cayman Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which the Fund is subject, such as tax risks, commodity related risks, and market and data risks.

 

Defiance Ether vs Bitcoin ETF | Commodity-Linked Derivatives Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Commodity-Linked Derivatives Tax Risk.  The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations, or other legally binding authority. As a RIC, the Fund must derive at least 90% of its gross income each taxable year from certain qualifying sources of income under the Code. If, as a result of any adverse future legislation, U.S. Treasury regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”), the income of the Fund from certain commodity-linked derivatives, including income from the Fund’s investments in the Subsidiary, were treated as non-qualifying income, the Fund may fail to qualify as RIC and/or be subject to federal income tax at the Fund level. The uncertainty surrounding the treatment of certain derivative instruments under the qualification tests for a RIC may limit the Fund’s use of such derivative instruments.

 

Defiance Ether vs Bitcoin ETF | Commodity Pool Regulatory Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Commodity Pool Regulatory Risk.  The Fund’s strategy will cause it to be deemed a commodity pool, thereby subjecting the Fund to regulation under the Commodities Exchange Act of 1936, as amended (the “CEA”) and CFTC rules. The Adviser is registered as a commodity pool operator (“CPO”) and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO imposes additional compliance obligations on the Adviser and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s registration as a CPO is not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.

 

Defiance Ether vs Bitcoin ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund intends to treat any income received by the Subsidiary as “qualifying income” under the provisions of the Code applicable to RICs. The IRS has issued numerous private letter rulings (“PLRs”) provided to third parties not associated with the Fund or its affiliates (which only those parties may rely on as precedent) concluding that similar arrangements resulted in qualifying income. Many of such PLRs have now been revoked by the IRS. In March of 2019, the IRS published Regulations that concluded that income from a corporation similar to the Subsidiary would be qualifying income. Although the Regulations do not require distributions from the Subsidiary, the Fund intends to cause the Subsidiary to make distributions that would allow the Fund to make timely distributions to its shareholders and to meet the requirement that the Subsidiary have a value not in excess of 25% of the Fund’s value at the close of a quarter. The Fund generally will be required to include in its own taxable income the income of the Subsidiary for a tax year, regardless of whether the Fund receives a distribution of the Subsidiary’s income in that tax year, and this income would nevertheless be subject to the distribution requirement for qualification as a regulated investment company and would be taken into account for purposes of the 4% excise tax.

 

If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objective and strategies. In the event that the Fund fails to qualify as a RIC, the Fund will promptly notify shareholders of the implications of that failure.

Defiance Ether vs Bitcoin ETF | Economic and Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.  The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Risk [Text Block]
  ● Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

Defiance Ether vs Bitcoin ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

  

● Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Risk [Text Block]
  ● Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

 

Defiance Ether vs Bitcoin ETF | Trading [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to just two underlying stocks as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. In the event of an unscheduled market close for derivatives that reference a single stock, such as either of the underlying company’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the relevant derivatives. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Reverse Repurchase Agreement Risk. Similar to borrowing, reverse repurchase agreements provide the Fund with cash for investment purposes, which creates leverage and subjects the Fund to the risks of leverage. Reverse repurchase agreements also involve the risk that the other party may fail to return the securities in a timely manner or at all. The Fund could lose money if it is unable to recover the securities and/or if the value of collateral held by the Fund, including the value of the investments made with cash collateral, is less than the value of securities.

Risk [Text Block]

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

 

Defiance Ether vs Bitcoin ETF | Ether Risk (Long Position) [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Ether Risk (Long Position). Through its long position in ether, the Fund is subject to the risk that ether’s value decreases. If the value of ether decreases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. Therefore, as a result of the Fund’s exposure to the value of ether, the Fund may also be subject to the following risks:

 

Ether is a relatively new and is subject to unique and substantial risks. The market for ether is subject to rapid price swings, changes and uncertainty. The further development of the Ethereum Network and the acceptance and use of ether are subject to a variety of factors that are difficult to evaluate. The slowing, stopping or reversing of the development of the Ethereum Network or the acceptance of ether may adversely affect the price and liquidity of ether. Ether is subject to the risk of fraud, theft, manipulation or security failures, operational or other problems that impact ether trading venues. Additionally, if one or a coordinated group of validators were to gain control of 33% or more of staked ether (i.e., ether that is deposited to support the Ethereum Network), they would have the ability to execute extensive attacks, manipulate transactions and fraudulently obtain ether. If such a validator or group of validators were to gain control of one-third of staked ether, they could halt payments. A significant portion of ether is held by a small number of holders sometimes referred to as “whales”. Transactions by these holders may influence the price of ether.

 

The value of ether may be substantially dependent on speculation, such that trading and investing in ether generally may not be based on fundamental analysis. The exposure of ether to instability and other speculative parts of the blockchain crypto industry, such as an event that is not necessarily related to the security or utility of the Etherum Network, can nonetheless precipitate a significant decline in the price of ether. There are risks related to fragmentation and lack of regulatory compliance with regard to crypto asset trading platforms. The crypto asset trading platforms upon which ether is traded and which may serve as a pricing source of the valuation of ether linked derivatives held by an Underlying Fund are or may become subject to enforcement actions by regulatory authorities.

 

Unlike the exchanges for more traditional assets, such as equity securities and futures contracts, ether and ether trading venues are largely unregulated. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote ether in a way that artificially increases the price of ether). Investors may be more exposed to the risk of theft, fraud and market manipulation than when investing in more traditional asset classes. Over the past several years, a number of ether trading venues have been closed due to fraud, failure or security breaches. Investors in ether may have little or no recourse should such theft, fraud or manipulation occur and could suffer significant losses.

 

The realization of any of these risks could result in a decline in the acceptance of ether and consequently a reduction in the value of ether, ether futures, Underlying Funds and the Fund. Additionally, legal or regulatory changes may negatively impact the operation of the Ethereum Network or restrict the use of ether. For example, if ether were determined to be or were expected to be determined to be a security under the federal securities laws, it is possible certain trading venues would no longer facilitate trading in ether, trading in ether futures may become significantly more volatile and/or completely halted, and the value of an investment in the Underlying Funds and/or the Fund could decline significantly and without warning, including to zero.

 

The creation of a “fork” or a substantial giveaway of ether (sometimes referred to as an “air drop”) may result in significant and unexpected declines in the value of ether, ether futures, Underlying Funds and the Fund. A fork may be intentional, such as the ‘Merge.’ The ‘Merge’ refers to protocol changes altering the method by which transactions are validated.

 

The market for ether futures may be less developed, and potentially less liquid and more volatile, than more established futures markets. While the ether futures market has grown substantially since ether futures commenced trading, there can be no assurance that this growth will continue. The price for ether futures contracts is based on a number of factors, including the supply of and the demand for ether futures contracts. Market conditions and expectations, regulatory limitations or limitations imposed by the listing exchanges or futures commission merchants (“FCMs”) (e.g., margin requirements, position limits, and accountability levels), collateral requirements, availability of counterparties, and other factors each can impact the supply of and demand for ether futures contracts, which can impact the Underlying Funds.

 

Market conditions and expectations, margin requirements, position limits, accountability levels, collateral requirements, availability of counterparties, and other factors may also limit the Underlying Funds’ ability to achieve their desired exposure to ether futures contracts, thereby impacting the Fund. If the Underlying Funds are unable to achieve their targeted exposure, the Fund may not be able to meet its investment objective and the Fund’s returns may be different or lower than expected. Additionally, collateral requirements may require Underlying Funds to liquidate their positions, potentially incurring losses and expenses, when it otherwise would not do so. Investing in derivatives like ether futures may be considered aggressive and may expose the Underlying Funds, and thereby the Fund, to significant risks. These risks include counterparty risk and liquidity risk.

 

The performance of ether futures contracts, in general, has historically been highly correlated to the performance of ether. However, there can be no guarantee this will continue. Transaction costs (including the costs associated with futures investing), position limits, the availability of counterparties and other factors may impact the cost of ether futures contracts and decrease the correlation between the performance of ether futures contracts and ether, over short or even long-term periods. In addition, the performance of back-month futures contracts (i.e., futures contracts whose delivery dates are relatively far in the future) is likely to differ more significantly from the performance of the spot prices of ether. To the extent the Underlying Funds are invested in back-month ether future contracts, their performance, and thereby the performance of the Fund, should be expected to deviate more significantly from the performance of ether.

Bitcoin Appreciation Risk (Short Position). By virtue of the Fund’s inverse exposure to changes in the value of bitcoin, the Fund is subject to the risk that bitcoin’s value increases. If the value of bitcoin increases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. Bitcoin is relatively new and the market for bitcoin is subject to rapid price swings, changes and uncertainty. Rapid increases in the value of bitcoin may result in substantial losses for the Fund. In addition, the broad acceptance and use of bitcoin would likely result in an increase in the value of bitcoin, which could result in significant losses for the Fund.

 

In addition, as a result of the Fund’s short exposure to the value of bitcoin, the Fund may also be subject to the following risks:

Defiance Ether vs Bitcoin ETF | Underlying Ether Funds – Long Exposure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Underlying Ether Funds – Long Exposure Risks: Investing in an Underlying Fund that focuses on ether, either through direct holdings or indirectly via derivatives like futures contracts and swaps, carries significant risks. These risks include high market volatility, which can be influenced by technological advancements, regulatory changes, and broader economic factors. When trading derivatives, liquidity risks and counterparty risks are substantial. Managing futures contracts can be complex and may affect the performance of an Underlying Fund. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Additionally, each Underlying Fund, and consequently the Fund, is dependent on blockchain technology, which brings technological and cybersecurity risks, along with custodial challenges for securely storing digital assets. The constantly evolving regulatory and legal landscape presents continuous compliance and valuation difficulties. Risks related to market concentration and network issues in the digital asset sector further add complexity. Moreover, operational intricacies in managing digital assets and potential market volatility can lead to losses for an Underlying Fund. These risks are magnified with respect to Underlying Funds that provide leveraged exposure to ether, which could lead to amplified losses for the Fund.

  ● Underlying Bitcoin Funds – Short Exposure Risks: The Fund seeks short exposure to Underlying Funds that focus on bitcoin (Underlying Bitcoin Funds) directly or through derivatives such as futures contracts and swaps. If the value of an Underlying Bitcoin Fund increases, the Fund will incur a loss, which could be substantial. Factors such as high market volatility, technological advancements, regulatory developments, and market concentration in the digital asset sector may cause the value of Underlying Bitcoin Funds to rise, negatively impacting the Fund’s performance. Underlying Bitcoin Funds’ use of derivatives subjects them to liquidity, counterparty, leverage, and futures risks, which can amplify price movements to the detriment of the Fund’s short position. Additionally, reliance on blockchain technology introduces technological, cybersecurity, and custodial risks that can cause further price increases. These risks are magnified with respect to Underlying Funds that provide leveraged exposure to bitcoin, which could lead to amplified losses for the Fund.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

 

Defiance Bitcoin vs Gold ETF | Bitcoin Risk (Long Position) [Member]

Risk [Text Block]

Bitcoin Risk (Long Position). Through its long position in bitcoin, the Fund is subject to the risk that bitcoin’s value decreases. If the value of bitcoin decreases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. Therefore, as a result of the Fund’s exposure to the value of bitcoin, the Fund may also be subject to the following risks:

 

The risks associated with bitcoin include the possibility of fraud, theft, market manipulation, and security breaches in trading platforms. A small group of large bitcoin holders, known as “whales,” can significantly influence bitcoin’s price and may have the ability to manipulate the price. The largely unregulated nature of bitcoin and its trading venues heightens risks of fraudulent activities and market manipulation, which could affect bitcoin’s price. For example, if a group of miners gains control over a majority of the bitcoin network, they could manipulate transactions to their advantage. Historical instances have seen bitcoin trading venues shut down due to fraud or security breaches, often leaving investors without recourse and facing significant losses.

 

Updates to bitcoin’s software, proposed by developers, can lead to the creation of new digital assets, or “forks,” if not broadly adopted. This can impact bitcoin’s demand and the Fund’s performance. The extreme volatility of bitcoin’s market price can result in shareholder losses. Furthermore, the operation of bitcoin trading platforms may be disrupted or cease altogether due to various issues, further affecting bitcoin’s price and the Fund’s investments.

 

The value of bitcoin has historically been subject to significant speculation, making trading and investing in bitcoin reliant on market sentiment rather than traditional fundamental analysis.

 

Bitcoin’s price can be influenced by events unrelated to its security or utility, including instability in other speculative areas of the crypto/blockchain space, potentially leading to substantial declines in its value.

 

Risks associated with crypto asset trading platforms include fragmentation, regulatory non-compliance, and the possibility of enforcement actions by regulatory authorities, which could impact the valuation of bitcoin-linked derivatives held by the Fund.

 

The security of the Bitcoin Blockchain may be compromised if a single miner or group controls more than 50% of the network’s hashing power, where hashing power refers to the computational capacity used to validate and secure transactions on the blockchain.

 

Proposed changes to the bitcoin protocol may not be universally adopted, leading to the creation of competing blockchains (forks) with different assets and participants, exemplified by past forks like Bitcoin Cash and Bitcoin SV.

 

The Bitcoin Blockchain protocol may contain vulnerabilities that attackers could exploit to disrupt its operation, potentially compromising the security and reliability of the network.

 

Emerging alternative public blockchains, particularly those emphasizing privacy through technologies like zero-knowledge cryptography, pose risks and challenges to the dominance of the Bitcoin Blockchain as a payment system.

 

Common impediments to adopting the Bitcoin Blockchain as a payment network include slow transaction processing, variability in transaction fees, and the volatility of bitcoin’s price, which may deter widespread adoption by businesses and consumers.

 

The development and use of “Layer II solutions” are critical for the scalability and functionality of the Bitcoin Blockchain, but they also introduce risks such as off-chain transaction execution, which could affect transparency and security. Layer II solutions are off-chain protocols that improve scalability and reduce transaction costs by processing transactions outside the main blockchain network.

 

Adoption and use of other blockchains supporting advanced applications like smart contracts present challenges to the dominance of the Bitcoin Blockchain, potentially impacting its long-term relevance and utility in the evolving landscape of blockchain technology.

 

Defiance Bitcoin vs Gold ETF | Digital Assets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Digital Assets Risk. Digital assets like bitcoin, designed as mediums of exchange, are still an emerging asset class and are not presently widely used as such. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated or possibly operating out of compliance with regulations, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility.

 

The digital asset market has experienced considerable volatility, leading to market disruptions and erosion of confidence among market participants. This instability and the resultant negative publicity could adversely affect the Fund’s reputation and trading prices. Ongoing market turbulence could significantly impact the value of the Fund’s share.

 

Blockchain technology, which underpins bitcoin and other digital assets, is relatively new, and many of its applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology.

 

Defiance Bitcoin vs Gold ETF | Leveraging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leveraging Risk. The Fund’s use of leverage amplifies both potential gains and potential losses, which can result in significant volatility and higher risk for investors. Specifically, bitcoin, the Fund’s leveraged long position (“Long Position”) and, gold, the leveraged short position (“Short Position”), expose the Fund to heightened risk if the Long Position performs poorly while the Short Position performs well.

 

If the value of the Long Position declines, the Fund’s leveraged exposure could result in losses that are magnified by the leverage factor, potentially exceeding the losses that would occur in an unleveraged position. For example, if the Fund’s Long Position is at +200% of net assets, a 10% decline in the value of the Long Position could translate into a 20% loss for the Fund’s net asset value attributable to that position.

 

Conversely, if the value of the Short Position increases, the Fund’s leveraged short exposure could also lead to magnified losses. If the Short Position is at -200% of net assets, a 10% rise in the value of the Short Position could result in a 20% loss for the Fund’s net asset value attributable to that position.

 

In scenarios where the Long Position underperforms and the Short Position outperforms simultaneously, the Fund could experience compounded losses from both positions. This dual risk could lead to significant declines in the Fund’s net asset value, particularly because the losses from one position may not be sufficiently offset by gains in the other, especially when leverage is applied.

 

Investors should be aware that the use of leverage increases the Fund’s sensitivity to market movements and can lead to substantial losses in a relatively short period. The Adviser’s active management and rebalancing efforts, while designed to manage exposure levels, cannot eliminate the inherent risks associated with leveraged positions. As such, the Fund may experience periods of extreme volatility, and the potential for loss is significant, particularly if market conditions do not align with the Fund’s investment strategy.

Opposing Performance Risks: The Fund’s strategy of holding a long position in one asset and a short position in another asset involves significant risks. From time to time, both positions may experience losses (i.e., the value of the asset held long declines, while the value of the asset held short increases). Such outcomes could occur due to a range of factors, including adverse market conditions, unexpected developments, or macroeconomic events that create opposing price movements in the paired securities.

 

Defiance Bitcoin vs Gold ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s derivative investments carry risks such as an imperfect match between the derivative’s performance and its underlying asset, and the potential for loss of principal, which can exceed the initial investment. Additionally, there are risks related to the possible default of the transaction’s counterparty and the illiquidity of derivatives, making them hard to sell or trade. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding. The derivatives used by the Fund will give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss. Certain of the Fund’s transactions in derivatives could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

  ● Futures. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract.

     

Defiance Bitcoin vs Gold ETF | Swaps [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Swaps. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. The Fund’s swap agreements are subject to mandatory clearing, which means they must be transacted through a futures commission merchant and cleared through a clearinghouse that serves as a central counterparty. Swaps involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a swap due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the swap in a bankruptcy or other reorganization proceeding. This risk is heightened with respect to OTC instruments, such as the swaps in which the Fund will invest, and may be greater during volatile market conditions. Other risks include the inability to close out a position because the trading market becomes illiquid (particularly in the OTC markets) or the availability of counterparties becomes limited for a period of time. Certain of the Fund’s transactions in swaps could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

 

Defiance Bitcoin vs Gold ETF | Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Options. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the underlying asset. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. If the Fund sells an option, it sells to another person the right to buy from or sell to the Fund (i.e., “call” or “put,” respectively) a specific amount of the underlying asset at an agreed-upon price, typically in exchange for a premium received by the Fund. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well-conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile, and the use of options can lower total returns.

 

Defiance Bitcoin vs Gold ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.

 

Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

Short Sales Risk. In connection with a short sale of a security or other instrument, the Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases, the Fund will experience a loss, which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase.

  ● Potentially No 1940 Act Protections. It is expected that one or more Underlying Funds will not be registered as an investment company subject to the 1940 Act. In addition, Underlying Funds that invest directly in bitcoin or gold are not subject to the 1940 Act. Accordingly, investors in such an Underlying Fund would not have the protections expressly provided by that statute, including: provisions preventing Underlying Fund insiders from managing an Underlying Fund to their benefit and to the detriment of shareholders; provisions preventing an Underlying Fund from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing Underlying Fund earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in an Underlying Fund’s character without the consent of shareholders. The Fund’s investments are subject to loss as a result of these risks.

Cayman Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which the Fund is subject, such as tax risks, commodity related risks, and market and data risks.

Commodity-Linked Derivatives Tax Risk.  The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations, or other legally binding authority. As a RIC, the Fund must derive at least 90% of its gross income each taxable year from certain qualifying sources of income under the Code. If, as a result of any adverse future legislation, U.S. Treasury regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”), the income of the Fund from certain commodity-linked derivatives, including income from the Fund’s investments in the Subsidiary, were treated as non-qualifying income, the Fund may fail to qualify as RIC and/or be subject to federal income tax at the Fund level. The uncertainty surrounding the treatment of certain derivative instruments under the qualification tests for a RIC may limit the Fund’s use of such derivative instruments.

Commodity Pool Regulatory Risk.  The Fund’s strategy will cause it to be deemed a commodity pool, thereby subjecting the Fund to regulation under the Commodities Exchange Act of 1936, as amended (the “CEA”) and CFTC rules. The Adviser is registered as a commodity pool operator (“CPO”) and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO imposes additional compliance obligations on the Adviser and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s registration as a CPO is not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.

Tax Risk. The Fund intends to treat any income received by the Subsidiary as “qualifying income” under the provisions of the Code applicable to RICs. The IRS has issued numerous private letter rulings (“PLRs”) provided to third parties not associated with the Fund or its affiliates (which only those parties may rely on as precedent) concluding that similar arrangements resulted in qualifying income. Many of such PLRs have now been revoked by the IRS. In March of 2019, the IRS published Regulations that concluded that income from a corporation similar to the Subsidiary would be qualifying income. Although the Regulations do not require distributions from the Subsidiary, the Fund intends to cause the Subsidiary to make distributions that would allow the Fund to make timely distributions to its shareholders and to meet the requirement that the Subsidiary have a value not in excess of 25% of the Fund’s value at the close of a quarter. The Fund generally will be required to include in its own taxable income the income of the Subsidiary for a tax year, regardless of whether the Fund receives a distribution of the Subsidiary’s income in that tax year, and this income would nevertheless be subject to the distribution requirement for qualification as a regulated investment company and would be taken into account for purposes of the 4% excise tax.

 

If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objective and strategies. In the event that the Fund fails to qualify as a RIC, the Fund will promptly notify shareholders of the implications of that failure.

Prospectus [Line Items]  
Risk [Text Block]

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.  The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Risk [Text Block]
  ● Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

Defiance Bitcoin vs Gold ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

Risk [Text Block]
  ● Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Prospectus [Line Items]  
Risk [Text Block]
  ● Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to just two underlying stocks as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. In the event of an unscheduled market close for derivatives that reference a single stock, such as either of the underlying company’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the relevant derivatives. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

High Portfolio Turnover Risk. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Reverse Repurchase Agreement Risk. Similar to borrowing, reverse repurchase agreements provide the Fund with cash for investment purposes, which creates leverage and subjects the Fund to the risks of leverage. Reverse repurchase agreements also involve the risk that the other party may fail to return the securities in a timely manner or at all. The Fund could lose money if it is unable to recover the securities and/or if the value of collateral held by the Fund, including the value of the investments made with cash collateral, is less than the value of securities.

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

 

Defiance Bitcoin vs Gold ETF | Gold Appreciation Risk (Short Position) [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Gold Appreciation Risk (Short Position). By virtue of the Fund’s inverse exposure to changes in the value of gold, the Fund is subject to the risk that gold’s value increases. If the value of gold increases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. As a result of the Fund’s short exposure to the value of gold, the Fund may also be subject to the following risks:

 

The Fund’s short gold exposure is subject to significant risk due to the inherent volatility and unpredictability of the commodities markets. The value of the Fund’s investments is typically derived from the price movements of physical gold or related economic variables. Price fluctuations in gold linked investments can be swift and substantial, often showing a low correlation with the returns of traditional equity and bond markets and may not align with trends in other asset classes.

 

Numerous factors can influence the price of gold, including overall market movements, interest rate changes, and variations in global supply and demand. Additionally, the volume of gold imports and exports, production factors such as weather conditions, and technological advances in gold processing and mining can significantly impact gold prices.

 

Increased hedging activities, economic conditions, regulatory developments, and political stability also play crucial roles in the price of gold. Furthermore, global supply and demand dynamics, political and economic events, inflation expectations, currency exchange rates, and investment activities of hedge funds and commodity funds can all affect gold prices. Sharp fluctuations in gold markets may result in significant losses for the Fund.

 

Defiance Bitcoin vs Gold ETF | Underlying Bitcoin Funds – Long Exposure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Underlying Bitcoin Funds – Long Exposure Risks: Investing in an Underlying Fund that focuses on bitcoin, either through direct holdings or indirectly via derivatives like futures contracts and swaps, carries significant risks. These risks include high market volatility, which can be influenced by technological advancements, regulatory changes, and broader economic factors. When trading derivatives, liquidity risks and counterparty risks are substantial. Managing futures contracts can be complex and may affect the performance of an Underlying Fund. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Additionally, each Underlying Fund, and consequently the Fund, is dependent on blockchain technology, which brings technological and cybersecurity risks, along with custodial challenges for securely storing digital assets. The constantly evolving regulatory and legal landscape presents continuous compliance and valuation difficulties. Risks related to market concentration and network issues in the digital asset sector further add complexity. Moreover, operational intricacies in managing digital assets and potential market volatility can lead to losses for an Underlying Fund. These risks are magnified with respect to Underlying Funds that provide leveraged exposure to bitcoin, which could lead to amplified losses for the Fund.

 

Defiance Bitcoin vs Gold ETF | Underlying Gold Funds – Short Exposure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Underlying Gold Funds – Short Exposure Risks: The Fund seeks short exposure to Underlying Funds that invest in gold (Underlying Gold Funds), either through direct holdings of physical gold or indirectly through derivatives such as futures contracts and swaps. Short exposure carries unique risks that differ from traditional long investments. If the value of an Underlying Gold Fund increases, whether due to rising gold prices, favorable market conditions, or effective management of the Underlying Gold Fund’s assets, the Fund will incur a loss, which could be substantial. Gold prices may increase as a result of factors such as inflation expectations, currency depreciation, geopolitical tensions, economic uncertainty, or changes in interest rates, any of which could cause Underlying Gold Funds to appreciate and negatively impact the Fund’s performance. Underlying Gold Funds that utilize derivatives are subject to liquidity risk, counterparty risk, leverage risk, and futures contracts risk, which can amplify price movements to the detriment of the Fund’s short position. In addition, Underlying Gold Funds that hold physical gold face custodial and safekeeping risks; successful navigation of these risks, or increases in the perceived value or demand for physical gold, could result in gains for Underlying Gold Funds and losses for the Fund. These risks are magnified with respect to Underlying Funds that provide leveraged exposure to gold, which could lead to amplified losses for the Fund, which could lead to amplified losses for the Fund.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Macroeconomic Factors: Economic uncertainty, inflation concerns, and currency devaluation in traditional financial markets can drive investors towards alternative assets like crypto assets, including bitcoin, as a hedge against economic instability. Additionally, monetary policies implemented by central banks, such as quantitative easing, can contribute to the devaluation of fiat currencies, making crypto assets more attractive as store of value assets. Such macroeconomic factors could cause the price of bitcoin to rise, which would negatively impact the Fund’s performance.

Defiance Gold vs Bitcoin ETF | Digital Assets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Digital Assets Risk. Digital assets like bitcoin, designed as mediums of exchange, are still an emerging asset class and are not presently widely used as such. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated or possibly operating out of compliance with regulations, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility.

 

The digital asset market has experienced considerable volatility, leading to market disruptions and erosion of confidence among market participants. This instability and the resultant negative publicity could adversely affect the Fund’s reputation and trading prices. Ongoing market turbulence could significantly impact the value of the Fund’s share.

 

Blockchain technology, which underpins bitcoin and other digital assets, is relatively new, and many of its applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology.

 

Defiance Gold vs Bitcoin ETF | Leveraging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leveraging Risk. The Fund’s use of leverage amplifies both potential gains and potential losses, which can result in significant volatility and higher risk for investors. Specifically, gold, the Fund’s leveraged long position (“Long Position”) and, bitcoin, the leveraged short position (“Short Position”), expose the Fund to heightened risk if the Long Position performs poorly while the Short Position performs well.

 

If the value of the Long Position declines, the Fund’s leveraged exposure could result in losses that are magnified by the leverage factor, potentially exceeding the losses that would occur in an unleveraged position. For example, if the Fund’s Long Position is at +200% of net assets, a 10% decline in the value of the Long Position could translate into a 20% loss for the Fund’s net asset value attributable to that position.

 

Conversely, if the value of the Short Position increases, the Fund’s leveraged short exposure could also lead to magnified losses. If the Short Position is at -200% of net assets, a 10% rise in the value of the Short Position could result in a 20% loss for the Fund’s net asset value attributable to that position.

 

In scenarios where the Long Position underperforms and the Short Position outperforms simultaneously, the Fund could experience compounded losses from both positions. This dual risk could lead to significant declines in the Fund’s net asset value, particularly because the losses from one position may not be sufficiently offset by gains in the other, especially when leverage is applied.

 

Investors should be aware that the use of leverage increases the Fund’s sensitivity to market movements and can lead to substantial losses in a relatively short period. The Adviser’s active management and rebalancing efforts, while designed to manage exposure levels, cannot eliminate the inherent risks associated with leveraged positions. As such, the Fund may experience periods of extreme volatility, and the potential for loss is significant, particularly if market conditions do not align with the Fund’s investment strategy.

 

Defiance Gold vs Bitcoin ETF | Opposing Performance Risks [Member]

Opposing Performance Risks: The Fund’s strategy of holding a long position in one asset and a short position in another asset involves significant risks. From time to time, both positions may experience losses (i.e., the value of the asset held long declines, while the value of the asset held short increases). Such outcomes could occur due to a range of factors, including adverse market conditions, unexpected developments, or macroeconomic events that create opposing price movements in the paired securities.

 

Defiance Gold vs Bitcoin ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s derivative investments carry risks such as an imperfect match between the derivative’s performance and its underlying asset, and the potential for loss of principal, which can exceed the initial investment. Additionally, there are risks related to the possible default of the transaction’s counterparty and the illiquidity of derivatives, making them hard to sell or trade. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding. The derivatives used by the Fund will give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss. Certain of the Fund’s transactions in derivatives could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

 

Defiance Gold vs Bitcoin ETF | Futures [Member]

  ● Futures. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract.

     

Defiance Gold vs Bitcoin ETF | Swaps [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Swaps. Swaps are entered into primarily with major global financial institutions for specified periods. The swaps in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. The Fund’s swap agreements are subject to mandatory clearing, which means they must be transacted through a futures commission merchant and cleared through a clearinghouse that serves as a central counterparty. Swaps involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a swap due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the swap in a bankruptcy or other reorganization proceeding. This risk is heightened with respect to OTC instruments, such as the swaps in which the Fund will invest, and may be greater during volatile market conditions. Other risks include the inability to close out a position because the trading market becomes illiquid (particularly in the OTC markets) or the availability of counterparties becomes limited for a period of time. Certain of the Fund’s transactions in swaps could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

     

Defiance Gold vs Bitcoin ETF | Options [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Options. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the underlying asset. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. If the Fund sells an option, it sells to another person the right to buy from or sell to the Fund (i.e., “call” or “put,” respectively) a specific amount of the underlying asset at an agreed-upon price, typically in exchange for a premium received by the Fund. A decision as to whether, when and how to use options involves the exercise of skill and judgment and even a well-conceived option transaction may be unsuccessful because of market behavior or unexpected events. The prices of options can be highly volatile, and the use of options can lower total returns.

 

Defiance Gold vs Bitcoin ETF | Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.

 

Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

Short Sales Risk. In connection with a short sale of a security or other instrument, the Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases, the Fund will experience a loss, which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase.

  ● Potentially No 1940 Act Protections. It is expected that one or more Underlying Funds will not be registered as an investment company subject to the 1940 Act. In addition, Underlying Funds that invest directly in gold or bitcoin are not subject to the 1940 Act. Accordingly, investors in such an Underlying Fund would not have the protections expressly provided by that statute, including: provisions preventing Underlying Fund insiders from managing an Underlying Fund to their benefit and to the detriment of shareholders; provisions preventing an Underlying Fund from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing Underlying Fund earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in an Underlying Fund’s character without the consent of shareholders. The Fund’s investments are subject to loss as a result of these risks.

 

Defiance Gold vs Bitcoin ETF | Cayman Subsidiary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cayman Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which the Fund is subject, such as tax risks, commodity related risks, and market and data risks.

Commodity-Linked Derivatives Tax Risk.  The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations, or other legally binding authority. As a RIC, the Fund must derive at least 90% of its gross income each taxable year from certain qualifying sources of income under the Code. If, as a result of any adverse future legislation, U.S. Treasury regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”), the income of the Fund from certain commodity-linked derivatives, including income from the Fund’s investments in the Subsidiary, were treated as non-qualifying income, the Fund may fail to qualify as RIC and/or be subject to federal income tax at the Fund level. The uncertainty surrounding the treatment of certain derivative instruments under the qualification tests for a RIC may limit the Fund’s use of such derivative instruments.

Prospectus [Line Items]  
Risk [Text Block]

Commodity Pool Regulatory Risk.  The Fund’s strategy will cause it to be deemed a commodity pool, thereby subjecting the Fund to regulation under the Commodities Exchange Act of 1936, as amended (the “CEA”) and CFTC rules. The Adviser is registered as a commodity pool operator (“CPO”) and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO imposes additional compliance obligations on the Adviser and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s registration as a CPO is not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.

 

Defiance Gold vs Bitcoin ETF | Tax Risk [Member]

Risk [Text Block]

Tax Risk. The Fund intends to treat any income received by the Subsidiary as “qualifying income” under the provisions of the Code applicable to RICs. The IRS has issued numerous private letter rulings (“PLRs”) provided to third parties not associated with the Fund or its affiliates (which only those parties may rely on as precedent) concluding that similar arrangements resulted in qualifying income. Many of such PLRs have now been revoked by the IRS. In March of 2019, the IRS published Regulations that concluded that income from a corporation similar to the Subsidiary would be qualifying income. Although the Regulations do not require distributions from the Subsidiary, the Fund intends to cause the Subsidiary to make distributions that would allow the Fund to make timely distributions to its shareholders and to meet the requirement that the Subsidiary have a value not in excess of 25% of the Fund’s value at the close of a quarter. The Fund generally will be required to include in its own taxable income the income of the Subsidiary for a tax year, regardless of whether the Fund receives a distribution of the Subsidiary’s income in that tax year, and this income would nevertheless be subject to the distribution requirement for qualification as a regulated investment company and would be taken into account for purposes of the 4% excise tax.

 

If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objective and strategies. In the event that the Fund fails to qualify as a RIC, the Fund will promptly notify shareholders of the implications of that failure.

Risk [Text Block]

Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.  The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Defiance Gold vs Bitcoin ETF | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

     

Defiance Gold vs Bitcoin ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

  ● Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

     

Defiance Gold vs Bitcoin ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

     

Defiance Gold vs Bitcoin ETF | Trading [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to just two underlying stocks as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. In the event of an unscheduled market close for derivatives that reference a single stock, such as either of the underlying company’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the relevant derivatives. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

Risk [Text Block]

High Portfolio Turnover Risk. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds and depositary accounts.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Reverse Repurchase Agreement Risk. Similar to borrowing, reverse repurchase agreements provide the Fund with cash for investment purposes, which creates leverage and subjects the Fund to the risks of leverage. Reverse repurchase agreements also involve the risk that the other party may fail to return the securities in a timely manner or at all. The Fund could lose money if it is unable to recover the securities and/or if the value of collateral held by the Fund, including the value of the investments made with cash collateral, is less than the value of securities.

 

Defiance Gold vs Bitcoin ETF | U.S. Government and U.S. Agency Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

 

Defiance Gold vs Bitcoin ETF | Bitcoin Appreciation Risk (Short Position) [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Bitcoin Appreciation Risk (Short Position). By virtue of the Fund’s inverse exposure to changes in the value of bitcoin, the Fund is subject to the risk that bitcoin’s value increases. If the value of bitcoin increases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. Bitcoin is relatively new and the market for bitcoin is subject to rapid price swings, changes and uncertainty. Rapid increases in the value of bitcoin may result in substantial losses for the Fund. In addition, the broad acceptance and use of bitcoin would likely result in an increase in the value of bitcoin, which could result in significant losses for the Fund.

 

In addition, as a result of the Fund’s short exposure to the value of bitcoin, the Fund may also be subject to the following risks:

Maintenance of Current Status: Bitcoin is the first and most well-known crypto asset, which is a significant advantage over other crypto assets.

Defiance Gold vs Bitcoin ETF | Underlying Bitcoin Funds – Short Exposure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Underlying Bitcoin Funds – Short Exposure Risks: The Fund seeks short exposure to Underlying Funds that focus on bitcoin (Underlying Bitcoin Funds) directly or through derivatives such as futures contracts and swaps. If the value of an Underlying Bitcoin Fund increases, the Fund will incur a loss, which could be substantial. Factors such as high market volatility, technological advancements, regulatory developments, and market concentration in the digital asset sector may cause the value of Underlying Bitcoin Funds to rise, negatively impacting the Fund’s performance. Underlying Bitcoin Funds’ use of derivatives subjects them to liquidity, counterparty, leverage, and futures risks, which can amplify price movements to the detriment of the Fund’s short position. Additionally, reliance on blockchain technology introduces technological, cybersecurity, and custodial risks that can cause further price increases. These risks are magnified with respect to Underlying Funds that provide leveraged exposure to bitcoin, which could lead to amplified losses for the Fund.

     

Defiance Gold vs Bitcoin ETF | Gold Risk (Long Position) [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Gold Risk (Long Position). Through its long position in gold, the Fund is subject to the risk that gold’s value decreases. If the value of gold decreases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. Therefore, as a result of the Fund’s exposure to the value of gold, the Fund may also be subject to the following risks:

 

The Fund will not invest directly in gold but will gain exposure through derivative instruments (e.g., gold futures contracts) and Underlying Funds. These investments are subject to significant risk due to the inherent volatility and unpredictability of the commodities markets. The value of these investments is typically derived from the price movements of physical gold or related economic variables. Price fluctuations in gold linked instruments can be swift and substantial, often showing a low correlation with the returns of traditional equity and bond markets and may not align with trends in other asset classes.

 

Numerous factors can influence the price of gold, including overall market movements, interest rate changes, and variations in global supply and demand. Additionally, the volume of gold imports and exports, production factors such as weather conditions, and technological advances in gold processing and mining can significantly impact gold prices. Increased hedging activities, economic conditions, regulatory developments, and political stability also play crucial roles. Furthermore, global supply and demand dynamics, political and economic events, inflation expectations, currency exchange rates, and investment activities of hedge funds and commodity funds can all affect gold prices. Sharp fluctuations in gold markets may result in potential losses. In addition, gold markets have experienced extended periods of flat or declining prices. Investors should also be aware that while gold is often used to preserve wealth, there is no assurance that it will maintain its long-term value in terms of purchasing power.

Prospectus [Line Items]  
Risk [Text Block]
  ● Underlying Gold Funds – Long Exposure Risks: Investing in an Underlying Fund that focuses on gold (Underlying Gold Funds), either through direct holdings or indirectly via derivatives like futures contracts, carries significant risk due to the inherent volatility and unpredictability of the commodities markets. Underlying Golds Funds that trade futures contracts are subject to derivatives risk, leverage risk, counterparty risk and futures contracts risk, among other risks. In addition, Underlying Gold Funds holding gold directly face significant custodial and safeguarding risks regarding their gold holdings. There is an inherent danger of these gold bars being lost, damaged, stolen, or becoming inaccessible due to factors such as natural disasters or terrorism. These risks are magnified with respect to Underlying Funds that provide leveraged exposure to gold, which could lead to amplified losses for the Fund.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.
