Cumulative bitcoin held after each disclosed event. The line steps rather than slopes because treasury positions change on purchase dates, not continuously.

About Capital B
Capital B, until November 2024 The Blockchain Group, launched Europe's first bitcoin treasury company programme with a one million euro capital increase in November 2024 that bought roughly 15 coins. Its stated target is 210,000 BTC, one percent of supply, by 2033.
What distinguishes it is the paperwork. Every acquisition is published as a regulated announcement through Euronext or Actusnews, stating the coins bought, the euro cost, the new cumulative total and a year to date BTC Yield. That makes the entire history reconstructable from primary sources, which is true of almost nothing else at this size.
The funding has come from a rolling series of small capital increases and convertible notes rather than one large raise, with Blockstream Capital Partners embedded in the structure. Momentum has faded sharply: after reaching 2,013 coins in July 2025 and 2,812 by September, growth through 2026 slowed to purchases of eight, then one, and BTC Yield fell from 1,410 percent to 2.13 percent year to date. It added a Cboe Europe listing in August 2026, where volume immediately exceeded its Paris home market.
