Michael Saylor’s publicly traded company Strategy (formerly MicroStrategy) buys additional Bitcoin after adding 1,587 BTC for $100 million during the period from June 8 to Sunday, according to a filing with the U.S. Securities and Exchange Commission. The purchase is made at an average price of $63,024 per bitcoin, which slightly lowers Strategy’s overall average cost basis to about $75,656.

Following the acquisition, Strategy’s total Bitcoin holdings reach 846,842 BTC, accumulated at a reported total cost of roughly $64.07 billion. Using market pricing around $66,216 per BTC, the holdings are valued at approximately $56.1 billion.

The company funds the purchase through sales of its Class A common stock (MSTR). In the same filing, Strategy reports raising about $209 million by selling 1.73 million MSTR shares over the week. Sources also report that Strategy’s preferred-share programs show no activity during the period.

The buys follow earlier commentary from Saylor referencing continued accumulation, and they come about two weeks after Strategy disclosed a small Bitcoin sale on June 1, its first reported sale in years.
