MicroStrategy, the Bitcoin strategy company, was still buying BTC from the market last week. But unlike previous disclosures, this time the official statement specifically highlighted their cash reserves, which increased from $62 million to $2.25 billion. The main source of this cash comes from issuing additional shares at market price through an ATM program and selling them to U.S. stock investors. In the past, the company mainly emphasized how much BTC they had purchased, but this time they rarely focused on their cash reserves. Previously, stock index company MSCI announced that on January 15 this year, they would decide whether to remove MicroStrategy from their stock index. Now, as the decision date approaches, MicroStrategy seems to be preparing cash reserves to defend against the potential impact of this event. The market generally predicts that if MSCI proceeds with this action, approximately $2.8 billion in related funds could flow out of these companies, which may also trigger other stock index issuers to follow suit.
