Corporate holder MicroStrategy has once again executed a "textbook" operation, spending $962.7 million to purchase 10,624 bitcoins between December 1 and 7, at an average purchase price of $90,615. This is the company's largest acquisition since July of this year. After this purchase, MicroStrategy's total bitcoin reserves have reached an astonishing 660,624 BTC, with a total cost of $4.935 billion and an average cost of $74,696. Notably, the company recently established a $1.4 billion cash reserve fund aimed at covering dividend and interest payments for the coming years. This has completely dispelled market concerns that it may be forced to sell bitcoin in the short term, providing a strong buffer for its "buy only, never sell" long-term strategy.
