Capital B raises €1.1M from Blockstream CEO Adam Back to boost Bitcoin treasury holdings.

Capital B, a French-listed Bitcoin treasury firm, secured €1.1 million through warrants fully subscribed by Blockstream CEO Adam Back, increasing his stake to nearly 10%. The funds will support Capital B's Bitcoin accumulation strategy, helping to strengthen its treasury holdings.
