Key Performance Metrics
As of the announcement date, Capital B reported a year-to-date BTC yield of 0.72% and a total bitcoin gain of 20.4 tokens.

The latest purchase follows a prior acquisition of 12 BTC earlier in March 2026, solidifying Capital B’s position as one of the largest publicly traded bitcoin holders in Europe.
Strategic Focus on Data and Decentralized Technology
