MicroStrategy bought another $1.5 billion in Bitcoin, marking the fourth consecutive week that the crypto hedge fund agency has bought Bitcoin. According to a filing with the U.S. Securities and Exchange Commission (SEC), MicroStrategy acquired 15,400 Bitcoins between November 25 and December 1. Since November 11, the company has purchased more than $13.5 billion in Bitcoin and currently holds about $38 billion in Bitcoin. MicroStrategy co-founder and chairman Michael Saylor has attracted Wall Street's attention by transforming the enterprise software maker into what he calls a "Bitcoin treasury." The company's stock price has soared more than 500% this year, outperforming almost all other major stocks. MicroStrategy has been financing Bitcoin transactions by selling convertible notes and issuing shares on the market. (Jinshi)
