The Motley Fool has positions in and recommends Bitcoin, Block, Inc., Coinbase Global, Inc., Goldman Sachs, PayPal Holdings, Tesla, and Visa. Since hitting an all-time high of almost $69,000 last November, Bitcoin's (CRYPTO: BTC) price has plunged about 70% as of this writing as investors have soured on risky assets. Because fiat currencies, like the U.S. dollar, lose value over time thanks to inflation, major corporations like Block, MicroStrategy, and Tesla have decided to allocate some cash on their balance sheets to Bitcoin.
