The Blockchain Group (ALTBG), a European bitcoin treasury company, has expanded its bitcoin reserves to 1,904 BTC after acquiring 116 BTC for approximately €10.7 million ($12.51 million).

This latest purchase follows a series of capital-raising activities, including an “ATM-type” equity issuance and a convertible bond offering completed in early July 2025.

Year-to-date, ALTBG has achieved a striking BTC yield of around 1,348%, underscoring the effectiveness of its treasury strategy.

Recent funding rounds saw contributions from investors like TOBAM and Adam Back, which facilitated the purchase of 11 BTC for about €1 million ($1.17 million) and an additional 105 BTC for nearly €9.8 million ($11.47 million).

The firm’s average acquisition cost sits at roughly €90,332 ($105,688) per bitcoin, bringing the total market value of its BTC holdings to an estimated €172 million ($201.24 million).
