$BTC

Bitcoin treasury company Strategy (formerly MicroStrategy) acquired an additional 13,390 BTC for approximately $1.34 billion at an average price of $99,856 per bitcoin between May 5 and May 11, according to an 8-K filing with the Securities and Exchange Commission on Monday.

Strategy now holds a total of 568,840 BTC — worth over $59 billion — bought at an average price of $69,287 per bitcoin for a total cost of around $39.4 billion, including fees and expenses, according to the company's co-founder and executive chairman, Michael Saylor. That's the equivalent of more than 2.7% of bitcoin's total 21 million supply and implies around $20 billion of paper gains — with 303,230 BTC bought in the last six months alone.

The latest acquisitions were made using proceeds from the sale of its class A common stock, MSTR, and perpetual strike preferred stock, STRK. Last week, Strategy sold 3,222,875 MSTR shares for approximately $1.31 billion. As of May 11, $19.69 billion worth of MSTR shares remain available for issuance and sale under that program, the firm said. Strategy also sold 273,987 STRK shares for approximately $25.1 million, with $20.85 billion worth of STRK shares remaining available for issuance and sale under that program.
