MicroStrategy (NASDAQ:MSTR) CEO Michael Saylor lays out some ways to utilize its ~122.5K bitcoin (BTC-USD) stash to generate income, according to the company's investor day presentation. To accomplish this, MicroStrategy (MSTR) could lend a portion of its bitcoin (BTC-USD) pile to a "trustworthy counterparty," Saylor said. "That could become a good source of income for us, or we could develop it with some kind of interesting applications." The company could also "put a mortgage against it and generate long-term debt under favorable circumstances, which we could leverage up against the bitcoin, he adds." Meanwhile, shares of MSTR, which are seen as a bitcoin proxy, close higher by 0.8%, though bitcoin (BTC-USD -3.3%) extends losses towards $46K. Towards the end of November, Saylor said his company bought more than 7K bitcoins in Q4.
