Analysis: MicroStrategy Would Only Become Insolvent if Bitcoin Drops to $18,826
According to Cointelegraph, Jeff Walton, a capital advisor, recently analyzed that even if Bitcoin’s price plunges by 80% below $20,000, MicroStrategy’s Bitcoin investment strategy remains solid. Walton calculated that the company would only become insolvent if Bitcoin falls to $18,826.
Charles Edwards, founder of quant fund Capriole Investments, pointed out that institutional demand for Bitcoin is experiencing explosive growth, marked by three key trends: First, MicroStrategy continues raising billions weekly to purchase Bitcoin; second, mining firm MARA is conducting a $1 billion financing round aiming to increase its Bitcoin holdings by 30%; third, institutions and ETFs now hold 13.5% of circulating Bitcoin supply—an exponentially growing share.
Edwards further predicted that current institutional adoption of Bitcoin is still in its early stages. He believes once Bitcoin surpasses the $100,000 threshold, it will trigger a much larger wave of market momentum.
