MicroStrategy, led by Michael Saylor, appears to have made another Bitcoin purchase, potentially marking its first acquisition with an average price over $100,000. Saylor hinted at the purchase through a post on Dec. 15, suggesting the firm's Bitcoin portfolio tracker might be missing an update. This follows a pattern of Sunday posts and Monday confirmations of Bitcoin buys. If confirmed, this would push MicroStrategy's Bitcoin holdings closer to a $50 billion valuation. The company's stock, MSTR, has surged 496.4% this year, securing a spot in the Nasdaq-100 index.
