MicroStrategy's net loss in Q4 was $12.5 billion, and many people are worried that Michael Saylor is selling coins to ease liquidity pressure. What is his red line for selling? As of February 1, he holds 713,502 Bitcoins, with an average purchase price of $76,052. According to AI financial modeling, there are three possible critical points. The first is the bankruptcy liquidation threshold around $20,000, which is the most extreme death red line. At this price, the 710,000 BTC held by MicroStrategy would be worth less than the approximately $14 billion total debt, and even if Saylor has an unwavering belief in never selling, legal liquidation and restructuring pressures will force asset disposal. The second is the credit collapse at $50,000. Once it falls below the $50,000 mark, market confidence will avalanche. Currently, the mNAV market cap is deeply discounted at a ratio of 0.67 to net assets, meaning the perpetual motion machine mode of issuing more shares to buy coins has completely stalled. The third is a 30-month life window. The good news is that MSTR has $2.25 billion in cash reserves, which is enough to cover interest and dividend payments for the next 30 months, even if the software business underperforms. This consideration is not just about a single price point but the speed at which cash reserves are depleted.
