(a)	Dismissal of Previous Independent Registered Public Accounting Firm

On June 16, 2026, Osprey Funds, LLC, as sponsor (the “Sponsor”) of Osprey Bitcoin Trust (the “Trust”) approved the dismissal of Grant Thornton LLP (“GT”) as the Trust’s independent registered public accounting firm, effective as of such date (the “Dismissal Date”).

The audit reports of GT on the Trust’s financial statements for the prior two fiscal years did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the Trust’s fiscal years ended December 31, 2024 and 2025 and the subsequent interim period through the Dismissal Date, there were (i) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K between the Trust and GT on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, any of which, if not resolved to GT’s satisfaction, would have caused GT to make reference thereto in its reports, and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K, except for the material weakness in internal control over financial reporting that is discussed in the Trust’s annual report on Form 10-K for the year ended December 31, 2025 and quarterly report on Form 10-Q for the quarter ended March 31, 2026 pertaining to ineffective oversight of the administrator process, which resulted in an audit adjustment to the Trust’s financial statements for the fiscal year ended December 31, 2025. The material weakness did not result in any material misstatements to the Trust’s financial statements. As reported in the Trust’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2026, the Trust continues efforts to remediate the material weakness, but the material weakness has not been fully remediated as of March 31, 2026, as management continues to evaluate the implementation and operation of remediation efforts.

The Trust requested that GT furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of such letter, dated June 22, 2026, is filed as Exhibit 16.1 to this Current Report on Form 8-K (the “Current Report”).

(b)	Engagement of New Independent Registered Public Accounting Firm

On June 17, 2026, Sponsor approved the engagement of Cherry Bekaert LLP (“Cherry Bekaert”) to serve as the Trust’s new independent registered public accounting firm for the fiscal year ending December 31, 2026, effective immediately (the “Engagement Date”). During the Trust’s fiscal years ended December 31, 2024 and 2025 and the subsequent interim period through the Engagement Date, neither the Trust nor anyone acting on its behalf consulted with Cherry Bekaert regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might have been rendered on the Trust’s financial statements and neither a written report nor oral advice was provided to the Trust that Cherry Bekaert concluded was an important factor considered by the Trust in reaching a decision as to any accounting, auditing, or financial reporting issue; or (ii) any matter that was the subject of a disagreement or a “reportable event” as described in Items 304(a)(1)(iv) and (v), respectively, of Regulation S-K.
