Positives

• Net assets increased by 20% to $4,243,952,000 at December 31, 2025, demonstrating growth in overall holdings.
• Significant Bitcoin contributions from Share creations, totaling approximately 18,375 Bitcoin with a value of $1,868,949,000 in 2025, indicate continued investor interest.
• The Trust employs robust security measures for Bitcoin custody, including cold storage, multiple encrypted private key shards, and geographical distribution of secure vaults, enhancing asset protection.

Negatives

• The Trust experienced a net decrease in net assets resulting from operations of $(437,219,000) for the year ended December 31, 2025, primarily due to Bitcoin price depreciation.
• Bitcoin's fair value depreciated from $93,390.22 per Bitcoin at December 31, 2024, to $87,549.41 per Bitcoin at December 31, 2025, indicating a challenging market for the underlying asset.
• Shares may trade at a premium or discount to the NAV per Share, potentially causing losses for investors who buy at a premium and sell at a discount, or vice versa.
• Shareholders have limited voting rights and restricted ability to bring derivative actions, requiring two or more non-affiliated shareholders collectively holding at least 10.0% of outstanding Shares for most derivative claims.
• The Trust irrevocably abandons Incidental Rights and IR Virtual Currency, meaning shareholders will not receive benefits from forks or airdrops of Bitcoin.
• Potential conflicts of interest exist due to the Sponsor's affiliates (Digital Currency Group, Inc.) having investments in other digital assets and ecosystem companies, and holding a minority interest in Kraken, one of the Digital Asset Trading Platforms included in the Index.
• The Trust lacks full insurance coverage for its Bitcoin holdings, and shareholders have limited legal recourse against the Trust and its service providers for potential losses.
• The U.S. federal income tax treatment of digital assets and the Trust's grantor trust status remains uncertain, which could lead to adverse tax consequences for shareholders.

Risks

• Extreme volatility of trading prices of digital assets, including Bitcoin, could have a material adverse effect on the value of the Shares and lead to substantial loss of value.
• The medium-to-long term value of the Shares is subject to factors relating to the capabilities and development of blockchain technologies, including potential for private key loss, internet dependence, network forks, energy consumption of mining, scaling challenges, open-source development issues, cryptographic flaws, and quantum computing threats.
• The digital asset industry is relatively new and rapidly evolving, and the value of the Shares depends on the acceptance of Bitcoin, which may be limited by factors such as selective acceptance as payment, banking service restrictions, and price determination by speculators.
• Digital assets may have concentrated ownership, and large sales or distributions by significant holders could adversely affect the market price of Bitcoin.
• If digital asset rewards for mining blocks and transaction fees are not sufficiently high, or if certain jurisdictions regulate mining activities, miners may cease expanding processing power or demand high transaction fees, negatively impacting Bitcoin value.
• A malicious actor or botnet obtaining control of more than 50% of the processing power on the Bitcoin Network could manipulate the Blockchain, adversely affecting the value of the Shares.
• A temporary or permanent fork or a clone of the Bitcoin Network could adversely affect the value of the Shares or the ability of the Trust to operate, and the Sponsor's discretion in choosing the 'appropriate' network may not align with the most valuable fork.
• Recent developments in the digital asset economy, including extreme volatility, disruption, loss of confidence in participants (e.g., FTX, Celsius, Voyager failures), and significant negative publicity, could have a material adverse effect on the value of the Shares.
• The largely unregulated nature and lack of transparency surrounding the operations of Digital Asset Trading Platforms may lead to fraud, market manipulation, business failures, security failures, or operational problems, adversely affecting Bitcoin value.
• Digital Asset Trading Platforms may be exposed to front-running and wash-trading, which could negatively affect market perception and Bitcoin prices.
• The Index used to calculate the value of the Trust's Bitcoin has a limited history, and its failure or volatility could adversely affect the value of the Shares.
• Competition from the emergence or growth of other digital assets (e.g., Ethereum, Solana), tokenized assets, central bank digital currencies (CBDCs), and other investment vehicles could negatively impact the demand for and price of Bitcoin.
• Congestion or delay on the Bitcoin Network may delay purchases or sales of Bitcoin by the Trust, reducing its attractiveness as a payment means.
• The Trust relies on third-party service providers (Custodial Entities, Authorized Participants, Liquidity Providers), and disruptions to their operations or their replacement could pose challenges to safekeeping Bitcoin or Trust operations.
• The legal rights of customers with respect to digital assets held by a third-party custodian in insolvency proceedings are currently uncertain, potentially exposing the Trust to loss of assets.
• The Shares may trade at a price that is at, above, or below the Trust's NAV per Share due to non-concurrent trading hours between NYSE Arca and the 24-hour Digital Asset Trading Platform Market.
• Any suspension or other unavailability of the Trust's redemption program may cause the Shares to trade at a discount to the NAV per Share.
• The amount of the Trust's assets represented by each Share will decline over time as the Trust pays the Sponsor's Fee and Additional Trust Expenses, potentially decreasing Share value.
• The value of the Shares may be influenced by factors unrelated to the value of Bitcoin, such as unanticipated operational problems, security vulnerabilities, or the introduction of privacy-enhancing features to the Bitcoin Network.
• Shareholders do not have the protections associated with ownership of shares in an investment company registered under the Investment Company Act or the protections afforded by the CEA.
• There is no guarantee that an active trading market for the Shares will continue to develop, which could adversely affect market prices and liquidity.

• Security threats to the Trust's Vault Balance or Settlement Balance could result in the halting of Trust operations, loss of assets, or damage to reputation.
• Bitcoin transactions are irrevocable, and stolen or incorrectly transferred Bitcoin may be irretrievable, leading to potential losses for the Trust.
• The lack of full insurance coverage for Bitcoin and shareholders' limited rights of legal recourse against the Trust and its service providers expose the Trust and its shareholders to the risk of loss.
• The Trust may be required, or the Sponsor may deem it appropriate, to terminate and liquidate at a time that is disadvantageous to shareholders.
• The Trust Agreement includes provisions that limit shareholders' voting rights and restrict their right to bring a derivative action, requiring a 10.0% ownership threshold by non-affiliated shareholders.
• The Sponsor is solely responsible for determining the value of the NAV and NAV per Share, and any errors, discontinuance, or changes in such calculations may adversely affect Share value.
• Extraordinary expenses resulting from unanticipated events (e.g., taxes, legal fees, indemnification) may become payable by the Trust, adversely affecting Share value through Bitcoin sales.
• The Trust's delivery or sale of Bitcoin to pay expenses could result in shareholders incurring tax liability without an associated distribution from the Trust.
• Intellectual property rights claims may adversely affect the Trust and the value of the Shares.
• Pandemics, epidemics, and other natural and man-made disasters could negatively impact the value of the Trust's holdings and/or significantly disrupt its affairs.
• The limited ability to facilitate in-kind creations and redemptions of Shares could have adverse consequences for the Trust, impairing the arbitrage mechanism.
• Shareholders will not receive the benefits of any forks or airdrops, as the Trust irrevocably abandons Incidental Rights and IR Virtual Currency.
• Coinbase Global serves as the Bitcoin custodian and prime execution agent for several competing exchange-traded Bitcoin products, which could adversely affect the Trust's operations if resources are not adequately allocated or if certain products are favored.
• Certain Authorized Participants may serve in a similar capacity for competing exchange-traded Bitcoin products, potentially affecting the arbitrage mechanism and the Trust's performance.
• Shareholders that are not Authorized Participants may only purchase or sell their Shares in secondary trading markets, and conditions in these markets may adversely affect their investment.
• Regulatory changes or actions by the U.S. Congress or any U.S. federal or state agencies may affect the value of the Shares or restrict the use of Bitcoin, mining activity, or the operation of the Bitcoin Network.
• A determination that Bitcoin or any other digital asset is a security may adversely affect the value of Bitcoin and the Shares, potentially leading to extraordinary expenses or termination of the Trust.
• Regulatory changes or other events in foreign jurisdictions may affect the value of the Shares or restrict the use of digital assets.
• If regulators or public utilities restrict or impact mining activities, there may be a significant decline in such activities, adversely affecting the Bitcoin Network and Share value.
• If regulators subject an Authorized Participant, the Trust, or the Sponsor to regulation as a money service business or money transmitter, it could result in extraordinary expenses and decreased liquidity for the Shares.
• Statutory or regulatory changes or interpretations could obligate the Trust or the Sponsor to register and comply with new regulations, resulting in potentially extraordinary, nonrecurring expenses.
• The treatment of the Trust for U.S. federal income tax purposes is uncertain, and if not classified as a grantor trust, it could face entity-level taxation.
• The treatment of digital assets for U.S. federal income tax purposes is uncertain, and future guidance could have an adverse effect on Bitcoin prices and Share value.
• Future developments in the treatment of digital assets for tax purposes other than U.S. federal income tax purposes could adversely affect the value of the Shares.

• Shareholders may be subject to withholding tax on income derived from forks, airdrops, and similar occurrences.
• Potential conflicts of interest may arise among the Sponsor or its affiliates and the Trust, as the Sponsor may favor its own interests or those of its affiliates.
• Shareholders cannot be assured of the Sponsor's continued services, and discontinuance without a suitable replacement could be detrimental to the Trust.
• If the Custodian resigns or is removed without replacement, it would trigger early termination of the Trust.
• Shareholders may be adversely affected by the lack of independent advisers representing investors in the Trust.

Future Outlook

The report highlights ongoing regulatory developments, including the SEC's crypto task force and Project Crypto initiative, aimed at modernizing securities rules for digital assets. It also mentions potential future legislation like the CLARITY Act. The Sponsor expects the Trust's cash balance to be zero at the end of each reporting period, as cash is primarily used to facilitate creation/redemption orders.

Management Comments

• The Sponsor believes that the security procedures in place for the Trust, including, but not limited to, offline storage, or cold storage, for a substantial portion of the Trusts Bitcoin, multiple encrypted private key shards, usernames, passwords and 2-step verification, are reasonably designed to safeguard the Trusts Bitcoin.
• The Sponsor believes that momentum pricing of Bitcoin has resulted, and may continue to result, in speculation regarding future appreciation in the value of Bitcoin, inflating and making the Index Price more volatile.
• The Sponsor believes that the Index Providers selection process for Constituent Trading Platforms as well as the methodology of the Index Prices algorithm provides a more accurate picture of Bitcoin price movements than a simple average of Digital Asset Trading Platform spot prices, and that the weighting of Bitcoin prices on the Constituent Trading Platforms limits the inclusion of data that is influenced by temporary price dislocations that may result from technical problems, limited liquidity or fraudulent activity elsewhere in the Bitcoin spot market.
• The Sponsor does not intend to permit the Trust to continue holding Bitcoin in a way that would violate the federal securities laws (and therefore would either dissolve the Trust or potentially seek to operate the Trust in a manner that complies with the federal securities laws, including the Investment Company Act).
• The Sponsor does not intend to dissolve the Trust on the basis that Bitcoin could at some future point be finally determined to be a security.
• The Sponsor expects that the Trust will not record any cash flow from its operations and that its cash balance will be zero at the end of each reporting period.

Industry Context

StockSavvy.ai notes that the digital asset industry is rapidly evolving, with significant regulatory scrutiny following major market disruptions like the FTX collapse. The introduction of CBDCs and financial institution initiatives leveraging blockchain technology pose competitive threats to Bitcoin's role as a medium of exchange or store of value. The SEC's ongoing efforts to establish a clear regulatory framework, including the 'crypto task force' and 'Project Crypto,' indicate a shift towards more structured oversight, which could impact the operational landscape for digital asset investment vehicles. The filing also highlights the concentration of market power in entities like Coinbase Global, which serves multiple competing Bitcoin ETPs, raising potential conflict of interest concerns across the industry.

Comparison to Industry Standards

• StockSavvy.ai observes that the Trust's 0.15% annual Sponsor's Fee is highly competitive within the spot Bitcoin ETF market, positioning it favorably against other offerings. For example, Grayscale Bitcoin Trust ETF (GBTC) has a 1.5% fee, while newer entrants like BlackRock's IBIT and Fidelity's FBTC have fees around 0.25% (with waivers).
• The Trust's ability to facilitate both in-kind and cash creations/redemptions aligns with best practices for arbitrage efficiency in ETPs, similar to other leading spot Bitcoin ETFs.
• The use of multiple custodians (Coinbase Custody and Anchorage Digital) for cold storage enhances security, a critical standard in the digital asset custody space, comparable to diversified custody solutions employed by other institutional-grade digital asset funds.

Key Dates

Recommendation

The Trust experienced a net decrease in net assets from operations in 2025, primarily due to Bitcoin price depreciation, indicating a challenging market environment. While the Trust offers a competitive fee structure and robust custody solutions, the inherent volatility of Bitcoin, coupled with regulatory uncertainties and limited shareholder rights, suggests a 'hold' recommendation. Investors should monitor Bitcoin market trends and regulatory developments closely before making further investment decisions.
