The company, the largest corporate holder of the cryptocurrency, continued a string of weekly purchases that began in early November.

MicroStrategy Inc., which is set to enter the Nasdaq 100 Index on Monday, announced it had purchased an additional $561 million of Bitcoin at an average price near last week’s record high.

MicroStrategy shares briefly surged on Monday before faltering to end nearly unchanged, after the software company and bitcoin stockpiler was selected to join the tech-heavy Nasdaq 100 index, further brightening the prospects of the stock.

Bitcoin broke another price record, rising above $107,000 Monday, after crossing $106,000 in late trading Sunday. Meanwhile, MicroStrategy, which calls itself a bitcoin treasury company, announced yet another $1.

MicroStrategy (NASDAQ:MSTR) acquired 5,262 bitcoin (BTC-USD) for a total of $561M for the week ended Dec. 22, the company disclosed on Monday, marking its seventh consecutive weekly bitcoin purchase.
