Item 4.01 Changes in Registrant’s Certifying Accountant.

(a) Dismissal of Independent Registered Public Accounting Firm

On March 30, 2026, the Board of Directors of BTCS Inc. (the “Company”), on the recommendation of the Audit Committee, approved the dismissal of RBSM LLP (“RBSM”) as the Company’s independent registered public accounting firm.

The reports of RBSM on the Company’s financial statements for the years ended December 31, 2025 and 2024 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. During the years ended December 31, 2025 and 2024 and the subsequent interim period through March 30, 2026, there were (i) no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K) between the Company and RBSM on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of RBSM would have caused RBSM to make reference thereto in its reports on the financial statements of the Company for such years, and (ii) no “reportable events” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

The Company has provided RBSM with a copy of the disclosures it is making in this Current Report on Form 8-K and requested that RBSM furnish a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made herein. A copy of RBSM’s letter will be filed as Exhibit 16.1 to this Current Report on Form 8-K.

(b) Appointment of New Independent Registered Public Accounting Firm

On March 30, 2026, following approval by the Company’s Board of Directors on the recommendation of the Audit Committee, the Company appointed Forvis Mazars, LLP (“FM”) as the Company’s new independent registered public accounting firm for the fiscal year ending December 31, 2026.

During the years ended December 31, 2025 and 2024 and the subsequent interim period through March 30, 2026, the effective date of FM’s appointment, neither the Company, nor any party on behalf of the Company, consulted with FM with respect to either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of the audit opinion that might be rendered with respect to the Company’s financial statements, and no written report or oral advice was provided to the Company by FM that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any matter that was subject to any disagreement (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).
