MicroStrategy (MSTR) has aggressively increased its Bitcoin holdings, purchasing over $3.7 billion worth in January 2026, despite Bitcoin's 30% price decline from its October 2025 high of $126,000. This move comes as MSTR's stock has plummeted over 60%, with its modified Net Asset Value (mNAV) dropping from 2.4 to 1.07, potentially presenting a buying opportunity for investors. The company's strategic expansion into the European market and increased interest from major financial institutions like Vanguard and Sumitomo Mitsui Trust Group highlight its growing influence. However, ongoing net outflows from Bitcoin spot ETFs and macroeconomic uncertainties pose challenges. With MSTR's premium reset and a significant drop in stock price, investors must weigh the potential for long-term gains against the risks of market volatility and debt obligations.
