Michael Saylor’s Strategy, the world’s largest public holder of Bitcoin, made its first BTC purchases in August, marking five years since adopting Bitcoin as a treasury asset.

Strategy acquired 155 Bitcoin (BTC) for $18 million during the week ending Sunday, according to a US Securities and Exchange Commission filing on Monday.

Strategy’s new Bitcoin purchases were made at an average price of $116,401 per coin, with BTC starting the week at $114,000 and nearing all-time highs around $122,000 by Sunday, according to CoinGecko.

The acquisition increased Strategy’s Bitcoin holdings to 628,946 BTC, purchased for about $46.1 billion at an average price of $73,288 per coin.

Strategy bought its first BTC on Aug. 11, 2020

Strategy’s latest Bitcoin acquisition coincides with the fifth anniversary of its BTC treasury strategy, launched on Aug. 11, 2020, with a $250 million buy of 21,454 BTC.

Since Strategy’s first BTC purchase, the price of Bitcoin has surged 960% from around $11,400 to about $120,000 at the time of writing, giving massive returns on the investment.

Despite the rising prices, Strategy, formerly known as MicroStrategy, has never stopped buying BTC since, now holding more than 600,000 BTC acquired over 74 purchases. 

“If you don’t stop buying Bitcoin, you won’t stop making money,” Strategy co-founder Saylor said in a post on X on Sunday.

In late 2024, Saylor pledged to keep buying Bitcoin no matter how high it surges. In June, the Strategy co-founder doubled down on his Bitcoin price forecast, predicting that BTC is going to hit $21 million in the next 21 years.

One of the smallest purchases on record

With Strategy celebrating five years of Bitcoin adoption as a treasury asset, its latest buy disappointed many observers.

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

While modest — especially compared with its 21,021 BTC purchase in July — the 155 BTC acquisition is not the smallest in Strategy’s history, but comes very close.

Strategy’s smallest Bitcoin purchase by BTC volume was in March, when it bought 130 BTC for $10.7 million in cash. By dollar value, the smallest was a $5 million acquisition of 155 BTC in November 2023, according to Strategy data.
