Michael Saylor, the founder and CEO of MicroStrategy, the company that holds the most Bitcoin of any public company, has hinted that he may be planning to buy more of the cryptocurrency. Saylor posted a chart of Sailortracker, a platform that tracks MSTR's BTC purchases, on his Twitter yesterday evening (KST). The media explained that "Saylor usually posts the chart before buying more BTC." Currently, MSTR holds 444,262 BTC, which is worth $41.4 billion. If Saylor does buy more BTC, it would be a further sign of his confidence in the cryptocurrency. Saylor has been a vocal proponent of Bitcoin for years, and he has repeatedly said that he believes it is a good investment. In an interview with CNBC in December 2020, Saylor said that "Bitcoin is the hardest money ever created." It remains to be seen whether Saylor will actually buy more BTC, but his recent tweet suggests that he is at least considering it. If he does, it would be a major boost for the cryptocurrency market.
