MicroStrategy bought another $1.50 billion in bitcoin, the crypto hedge fund agency's fourth consecutive week of buying. MicroStrategy acquired 15,400 bitcoins between Nov. 25 and Dec. 1, according to a SEC filing. Since Nov. 11, the company has bought more than $13.50 billion in bitcoin and currently holds about $38 billion in bitcoin. Michael Thaler, co-founder and chairperson of MicroStrategy, has turned the enterprise software maker into what he calls a "bitcoin treasury", drawing attention from Wall Street. The company's share price has surged more than 500% this year, outperforming almost every other major stock. MicroStrategy has been financing bitcoin trading by selling convertible notes and issuing shares in the market. (Golden Ten)
