Japanese cryptocurrency exchange Bitbank has become a wholly owned subsidiary of SBI Holdings following the completion of a full acquisition. The transaction was finalized through share repurchases from MIXI and Ceres, executing a previously announced agreement between the parties. Management changes accompany the ownership transfer, with SBI VC Trade President Tomohiko Kondo appointed as a Bitbank director. Bitbank CEO Noriyuki Hirosue will transition to an outside director role at SBI VC Trade. Bitbank stated that existing services remain unaffected and users can continue platform operations normally while leveraging SBI Group's financial resources and customer base for future development.
