MicroStrategy's stock performance has outperformed almost all large U.S. stocks in the past two years. Its co-founder and chairman Michael Saylor's unconventional decision to buy Bitcoin four years ago to offset inflation has driven a gain of more than 1,700%. MicroStrategy has shifted from using cash flow to issuing convertible notes to buy Bitcoin, and plans to explore other ways to fund more purchases. Saylor said he basically borrowed money at an interest rate of 1% to buy Bitcoin. Bloomberg expects that the new accounting system next year will turn the loss-making MicroStrategy into a profit as Bitcoin assets will be revalued at market value, which may lead to the company's net profit of $2 billion next year, compared with a loss of about $200 million this year.
