Capital B Boosts Bitcoin Reserves Through Strategic Capital Raises

The acquisition was made possible through two capital raises. On August 18, Capital B raised €2.2 million at €2.24 per share, fully subscribed by Bitcoin pioneer Adam Back, CEO of Blockstream, which helped acquire 21 BTC. Then, on September 16, the company completed a larger raise at €1.55 per share via an accelerated bookbuilding process. This round brought in €58.1 million, funding the purchase of 530 BTC for €52.6 million.

Combined, these two transactions added 551 BTC to Capital B’s reserves. As of September 22, the company holds 2,800 BTC, with a total acquisition cost of €261 million. The average price per Bitcoin across these purchases is approximately €93,205. 

Capital B’s Bitcoin approach has delivered strong results in this year. The company reports a year-to-date Bitcoin yield of 1,651.2%, with a quarterly yield of 27.8%. Since January, Capital B has added 660.5 BTC, including 496.3 BTC in the third quarter. These gains equal a euro-denominated increase of €65.6 million year-to-date and €49.3 million for the quarter. The performance shows that Capital B’s treasury model is not only about holding Bitcoin but also actively increasing Bitcoin per share over time.

Crypto Funds Attract $1.9B Amid Bitcoin ETF Growth

Amid these moves, cryptocurrency funds recorded a second consecutive week of inflows, extending the $3.3 billion gained the previous week. Crypto exchange-traded products (ETPs) brought in $1.9 billion last week, according to CoinShares data. Renewed investor interest follows the US Federal Reserve’s first interest rate cut of the year, a 0.25-point reduction last Wednesday. CoinShares’ Butterfill said the inflows reflect a positive reaction to the rate cut despite initial investor caution.

Bitcoin and Ether (ETH) led last week’s inflows, attracting $977 million and $772 million, respectively. Solana (SOL) and XRP (XRP) also saw strong demand, with $127 million and $69 million in inflows.

Digital asset investment products saw US$1.9bn of inflows last week. Bitcoin and Ethereum led with inflows of US$977m and US$772m respectively. Total AuM hit a YTD high of US$40.4bn, putting the market on track to match or slightly exceed last year’s US$48.6bn inflows.…
