MicroStrategy has bought another $2.1 billion worth of Bitcoin today, while selling a combination of stocks and fixed-income securities to provide funding for the rapidly increasing purchases, which has attracted more and more attention. This is the fifth consecutive Monday that the company has announced the purchase of digital assets. Michael Saylor, the co-founder and chairman of the company, decided that this small enterprise software manufacturer needed to take a different path to survival, and over the past four years, the Bitcoin he has accumulated is now worth more than $41 billion. In October of this year, he announced plans to raise $42 billion over the next three years through the sale of stocks and convertible bonds on the market, in order to accelerate its strategic transformation. The current danger is that the massive rebound in cryptocurrency over the past year could reverse, and leveraged bets on its value could have serious consequences for its owners in this scenario.
