French Company Drops €47M on Bitcoin — Stock Price Explodes

The Blockchain Group, a French company, has just acquired 580 bitcoins for 47 million euros, establishing itself as the first “Bitcoin Treasury Company“ in Europe. This strategy, inspired by Michael Saylor’s Strategy, has sparked a spectacular surge in its stock price.

An Ambitious Investment Strategy in Bitcoin

The Blockchain Group, a French company listed on Euronext Paris, confirmed on March 26, 2025, the acquisition of an additional 580 bitcoins, its largest operation to date.

This transaction, valued at 47.3 million euros (approximately 50.64 million dollars), was executed at an average price of 81,550 euros per bitcoin. The operation was financed by the proceeds from a convertible bond issuance announced on March 6.

This is the third purchase by the French company. Its first investment of 15 BTC took place on November 5, 2024, the day of Donald Trump’s election, followed by a second acquisition of 25 BTC on December 4, 2024, as bitcoin approached 100,000 dollars. These initial purchases occurred at key moments in the evolution of the crypto market.

With this new transaction, The Blockchain Group now holds a total of 620 bitcoins with an acquisition value of approximately 50.5 million euros.

The company, which presents itself as the “first Bitcoin Treasury Company in Europe“, is clearly inspired by the Strategy tactics, the American company of Michael Saylor that has recently crossed the threshold of 500,000 bitcoins.

The Blockchain Group has entrusted the execution and custody of its digital assets to Swissquote Bank Europe SA, a service provider registered with the Luxembourg regulator (CSSF).

Remarkable Stock Performances and a New Methodology

The stock of The Blockchain Group (ALTBG) has experienced a meteoric rise since the launch of its bitcoin investment strategy. The stock price has jumped 226% since its first acquisition in November, reaching 0.48 euros, according to Google Finance data.

To measure the effectiveness of its strategy, the company has adopted three new key performance indicators inspired by the practices of Strategy and Metaplanet (a Japanese company): the “BTC Yield“, the “BTC Gain“, and the “BTC € Gain“.

These metrics allow the assessment of the evolution of the ratio between the number of bitcoins held and the number of fully diluted shares outstanding.

The results are impressive: The Blockchain Group shows a “BTC Yield“ of 709.8% since the beginning of the year and a “BTC € Gain“ of over 23.1 million euros.

The company emphasizes, however, that these indicators do not constitute traditional financial measures and do not necessarily reflect the market value of its securities.

This trend of investment in bitcoin by publicly listed companies is also confirmed in the United States, where GameStop recently announced its intention to acquire crypto, causing a 12% rise in its stock. These movements illustrate the growing interest of public companies in bitcoin as a strategic reserve, despite the risks of volatility inherent in this asset class.
