French Bitcoin Treasury Firm Capital B Makes Largest Purchase in a Year

Capital B, a French bitcoin treasury company, announced its largest bitcoin purchase in twelve months, acquiring 376 BTC for €25.3 million, roughly $29.4 million. The move brings the firm’s total holdings to 3,521 BTC, accumulated for a combined €309.4 million, putting its average purchase price at about €87,878 per coin. The last time the company made a purchase of this size was in September of last year, when it acquired 551 BTC, following a much smaller buy of just 6 BTC the previous month.

Capital Raises Fund the Purchase

The latest acquisition was financed through recently completed fundraising efforts, including a private placement worth €28.7 million. That round included a fresh €7.6 million investment from Bitcoin advocate Adam Back, increasing his ownership stake in the company to 17.64% on an ordinary basis.

Strategy Shift and Market Context

Formerly known as The Blockchain Group, Capital B rebranded in mid-2025 to concentrate fully on its bitcoin treasury approach. The company has also been exploring a bitcoin-backed credit product for the European market, drawing inspiration from similar instruments offered by other treasury firms in the United States. Bitcoin itself traded around $79,500 on Monday, holding relatively steady after touching a local high near $81,700 the previous week before pulling back.
