MicroStrategy ($MSTR), a business intelligence and software company, has gained significant attention for its strategy of holding Bitcoin as a treasury reserve asset. Recently, the company sold 5.4 million shares, raising $2.1 billion, and has been increasing its Bitcoin holdings significantly. In November, MicroStrategy expanded its Bitcoin reserves by nearly 60%, now approaching 70%, bringing its total holdings to 402,100 Bitcoins. However, investors are paying nearly $240,000 per Bitcoin through MicroStrategy's stock, which is significantly above the market price. The company's use of convertible bonds for financing has been described as a strategic move, though concerns about overvaluation and the sustainability of its financing model persist. MicroStrategy shares were down 2.1% premarket following the share sale announcement. Despite these concerns, the company continues to attract attention for its unconventional approach to corporate treasury management.
