Saylor, the chief executive of business intelligence and software company MicroStrategy (MSTR), raised some eyebrows when he deployed $250 million of its balance sheet to buy bitcoin in August last year. The purchase marked the first time a publicly traded company invested in bitcoin as part of its capital allocation strategy. In September, he upped the ante and bought another $175 million worth of bitcoin. The move was followed by Jack Dorsey's Saylor made the boldest move in early December when he raised $650 million from a convertible bond offering and used the proceeds to buy another 29,646 bitcoins. As of December 21, MicroStrategy had spent a total of $1.125 billion on the 70,470 bitcoins that the company holds as its corporate Treasury reserve, according to an announcement.
