MicroStrategy Incorporated (NASDAQ: MSTR) is the biggest Bitcoin (CRYPTO: BTC) holder among U.S. companies, but the Michael Saylor-led company may have to shed some of it if the apex coin keeps on tumbling. The Borrowing: In March 2022, MicroStrategy borrowed $205 million from Silvergate Capital Corp’s (NYSE: SI) Silvergate Bank, collateralized against its Bitcoin holdings to buy cryptocurrency and pay fees, interest, and expenses linked to the loan transaction.
