• Strategy acquired 155 BTC for $18M, raising its Bitcoin treasury to 628,946 coins worth $46.1B.
• The purchase marks the 5th anniversary of Strategy’s Bitcoin adoption, which began in August 2020.
• Bitcoin’s price has surged ~960% in five years and is now trading near $120K per coin.

Michael Saylor’s firm, Strategy, has bought into its Bitcoin reserve again with 155 BTC acquired last week for about $18 million. At an average of $116,401 per coin, the purchase was made as per an SEC filing unveiled on Monday.

Through this latest investment, Strategy’s overall bitcoin hoard has reached 628,946 BTC. The firm has thus far invested approximately $46.1 billion into its inventory, with an average cost of $73,288 per coin.

Strategy Celebrates Bitcoin Anniversary

The acquisition date is notable as it falls on the anniversary of the adoption of Bitcoin by Strategy five years back. The process began on August 11, 2020, when the company bought 21,454 BTC valued at $250 million, as the then-price of Bitcoin was close to $11,400.

In five years, the price of Bitcoin has grown approximately 960%, currently sitting near $120,000. Strategy has made 74 distinct purchases of Bitcoin since 2020.

Michael Saylor celebrated the event, posting on X (formerly Twitter), tweeting: “If you don’t stop buying Bitcoin, you will not stop making money.”

Strategy Keeps Building Its Bitcoin Reserve

Though the purchase is notable in celebrating the anniversary, the 155 BTC purchase is one of the smallest of the company. To compare, its smallest purchase in volume happened in March 2025 for 130 BTC valued at $10.7 million, and the smallest in terms of dollar amount happened in November 2023 when 155 BTC cost $5 million.

“Only 155 BTC? Looks like you need to raise more fiat,” Coin Bureau founder Nic Puckrin commented on Saylor’s post on X.

On the other hand, the largest recent buy was in July 2025, when Strategy snapped up 21,021 BTC in a single day.

The firm has been unabashed in supporting its Bitcoin-first policy and has purchased consistently irrespective of market price. Saylor has also continuously maintained that the firm’s long-term game remains in Bitcoin and speculated in June 2025 that the future of Bitcoin will see it possibly touching 21 million coins as a maximum within two decades.

Every acquisition, including this recent one, is disclosed to the SEC, leaving the company’s Bitcoin reserve fully transparent.
