Business intelligence firm Strategy has made another bold move into the crypto market, purchasing an additional $50 million worth of Bitcoin (BTC), as announced on Monday. This marks the company’s largest buy since late September, with the latest coins acquired at an average price of $102,557 per BTC. The firm’s total Bitcoin holdings now stand at an impressive 641,692 BTC, further solidifying its position as one of the biggest corporate Bitcoin holders globally.

Despite the aggressive expansion, Strategy faces mounting criticism over its financial stability. The company’s stock has taken a hit, drawing skepticism from investors, including venture capitalist Jason Calacanis, who warned of potential collapse risks.

Adding to the concerns, S&P Global Ratings recently gave Strategy a B- credit rating, highlighting its heavy debt load and limited diversification. While the firm touts this as progress, reports from The Financial Times and The Wall Street Journal suggest that its Bitcoin-centric strategy could soon face major challenges.
