Strategy's co-founder Michael Saylor announced the acquisition of 4,020 BTC for $427 million, with an average price of $106,237 per Bitcoin.
The company now holds 580,250 BTC, acquired for over $40.6 billion at an average price of $69,979 per BTC, resulting in a paper gain of over $23 billion.
Despite BTC's surge to a new all-time high above $109,000, Strategy's stock price dropped, closing under $370 at Friday's close.
Saylor emphasized only buying Bitcoin with money he 'can't afford to lose', as Strategy continues to expand its cryptocurrency holdings.
