Important Information and Where to Find It

BCSA will file with the SEC a registration statement on Form S-4 that will include a proxy statement with respect to BCSA’s shareholder meeting to vote on the proposed Business Combination as well as its warrant holder meeting to vote on proposed changes to the agreement governing BCSA’s outstanding public warrants. The registration statement will also include a prospectus with respect to securities to be issued in connection with the Business Combination. This filing does not contain all the information that investors should consider concerning the proposed Business Combination and is not intended to form the basis of any investment decision or any other decision in respect of the Business Combination. BCSA and Linqto urge their investors, shareholders and other interested persons to read, when available, the preliminary proxy statement/prospectus as well as other documents that BCSA and Linqto have filed or will file with the SEC because these documents will contain important information about BCSA, Linqto and the transaction. After the registration statement is declared effective, the definitive proxy statement/prospectus to be included in the registration statement will be mailed to shareholders and warrant holders of BCSA as of a record date to be established for voting on the proposed Business Combination and the related amendment to the agreement governing the public warrants, respectively. Once available, shareholders and warrant holders of BCSA will also be able to obtain a copy of the registration statement on Form S-4, including the proxy statement/prospectus, and other documents filed with the SEC without charge, by directing a request to: Blockchain Coinvestors Acquisition Corp. I, PO Box 1093, Boundary Hall Cricket Square, Grand Cayman KY1-1102, Cayman Islands, Attn: Secretary.

Participants in the Solicitation

BCSA and Linqto and their respective directors, executive officers, other members of management, and employees may, under SEC rules, be deemed to be participants in the solicitation of proxies of BCSA’s shareholders and warrant holders with respect to the potential transaction described in this filing. Information about the persons who may, under SEC rules, be deemed to be participants in the solicitation of BCSA’s shareholders and warrant holders in connection with the potential transaction will be set forth in BCSA’s registration statement on Form S-4 containing the preliminary proxy statement/prospectus when it is filed with the SEC. BCSA’s shareholders and warrant holders will be able to obtain copies of the preliminary proxy statement/prospectus, the definitive proxy statement/prospectus and other documents filed with the SEC, once available, free of charge at the SEC’s website at www.sec.gov or by directing a request to: Blockchain Coinvestors Acquisition Corp.
