STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K (the “Annual Report”) includes “forward-looking statements” with respect to the financial conditions, results of operations, plans, objectives, future performance and business of Bitwise Bitcoin ETF (the “Trust”). In some cases, you can identify forward-looking statements by terminology such as “may,” “might,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “continue,” or the negative of these terms and other similar expressions are intended to identify some of the forward-looking statements. All statements (other than statements of historical fact) included in this Annual Report that address activities, events, or developments that will or may occur in the future, including such matters as movements in the digital asset markets, the Trust’s operations, the plans of Bitwise Investment Advisers, LLC (the “Sponsor”), and references to the Trust’s future success and other similar matters, are forward-looking statements. These statements are only predictions. Actual events or results may differ materially from such statements. These statements are based upon certain assumptions and analyses the Sponsor has made based on its perception of historical trends, current conditions, and expected future developments, as well as other factors appropriate in the circumstances.

Whether or not actual results and developments will conform to the Sponsor’s expectations and predictions is subject to a number of risks and uncertainties, including, but not limited to, those described in “Item 1A. Risk Factors.”

Factors which could have a material adverse effect on the Trust’s business, financial condition or results of operations and future prospects or which could cause actual results to differ materially from the Trust's expectations include, but are not limited to:

•

the special considerations discussed in this Annual Report;

•

the extreme volatility of trading price that bitcoin has experienced in recent periods and may continue to experience, which could have a material adverse effect on the value of the Shares of the Trust (plural, the “Shares” or singular, a “Share”);

•

the recentness of the development of bitcoin and other crypto assets, and the uncertain medium-to-long term value of the Shares due to a number of factors relating to the capabilities and technology developments regarding the use of bitcoin and other crypto assets and to the fundamental investment characteristics of bitcoin and other crypto assets;

•

the value of the Shares depending on the acceptance of bitcoin and blockchain technologies, a new and rapidly evolving industry;

•

the unregulated nature and lack of transparency surrounding the operations of blockchain technologies and crypto assets, which may adversely affect the value of bitcoin and the Shares;

•

the limited history of the Trust;

•

the possibility that the Shares may trade at a price that is at, above or below the Trust’s NAV per Share;

•

changes in laws or regulations, or actions taken by governmental authorities or U.S. federal or state regulatory bodies, including the Securities and Exchange Commission (the “SEC” or the “Commission”) and the Commodity Futures Trading Commission, that may affect the value of the Shares or restrict the use of bitcoin or other crypto assets, the mining activity or the operation of the Bitcoin network, or the bitcoin market in a manner that adversely affects the value of the Shares;

•

the possibility that the Trust or the Sponsor could be subject to regulation as a money service business or money transmitter, which could result in extraordinary expenses to the Trust or the Sponsor and also result in decreased liquidity for the Shares;

•

regulatory changes or interpretations that could obligate the Trust or the Sponsor to register and comply with new regulations, resulting in potentially extraordinary, nonrecurring expenses to the Trust;

•

potential conflicts of interest that may arise among the Sponsor or its affiliates and the Trust;

•

the Trust’s reliance on the security, stability, and performance of its service providers, including the Bitcoin Custodian, Cash Custodian, Prime Execution Agent, and other intermediaries, which may be subject to operational failures, conflicts of interest, and regulatory actions, potentially adversely affecting its operations and the value of the Shares;

•

general economic, market and business conditions, and political developments, including, without limitation, global pandemics and the societal and government responses thereto, which could negatively impact the value of the Trust’s holdings in bitcoin and significantly disrupt its operations; and

•

any additional risk factors discussed in “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Annual Report, as well as those described from time to time in the Trust’s future reports filed with the SEC.

All the forward-looking statements made in this Annual Report are qualified by these cautionary statements, and there can be no assurance that the actual results or developments the Sponsor anticipates will be realized or, even if substantially realized, that they will result in the expected consequences to, or have the expected effects on, the Trust’s operations or the value of the Shares.

Should one (1) or more of these risks discussed in the section entitled “Risk Factors” under Item 1A – Risk Factors of this Annual Report or other uncertainties materialize, or should underlying assumptions prove incorrect, actual outcomes may vary materially from those described in forward-looking statements. Forward-looking statements are made based on the Sponsor’s beliefs, estimates and opinions on the date the statements are made, and neither the Trust nor the Sponsor is under a duty to update any of the forward-looking statements to conform such statements to actual results or to reflect a change in the Sponsor’s expectations or predictions, other than as required by applicable laws. Investors are therefore cautioned against relying on forward-looking statements.
