Michael Saylor’s Strategy, the largest public holder of Bitcoin, marked the fifth anniversary of its BTC treasury strategy with a fresh $18 million purchase. According to a U.S. Securities and Exchange Commission filing, the company acquired 155 BTC during the week ending Sunday, at an average price of $116,401 per coin. Bitcoin started the week at $114,000 and closed near $122,000, brushing against all-time highs.

The acquisition brings Strategy’s total Bitcoin stash to 628,946 BTC, worth roughly $46.1 billion at an average purchase price of $73,288. The firm’s Bitcoin journey began on August 11, 2020, with a $250 million purchase of 21,454 BTC. Since then, the price has surged about 960%, from $11,400 to nearly $120,000, delivering massive gains.

Despite the milestone, this latest buy is one of the smallest in the company’s history. Strategy’s smallest-ever purchase by BTC volume came in March 2025 with 130 BTC for $10.7 million. By dollar value, the record low was $5 million for 155 BTC in November 2023. In contrast, July 2025 saw a massive 21,021 BTC purchase.

Critics were quick to point out the modest scale. Coin Bureau founder Nic Puckrin quipped on X, “Only 155 BTC? Looks like you need to raise more fiat.” Saylor, unfazed, reiterated his long-term commitment, famously stating, “If you don’t stop buying Bitcoin, you won’t stop making money.” In June, he predicted Bitcoin could reach $21 million in the next 21 years.

Over the past five years, Strategy (formerly MicroStrategy) has executed 74 Bitcoin purchases, never selling a single coin, cementing its position as the world’s most relentless institutional BTC accumulator.
