MicroStrategy is unique on the stock market because it essentially acts like a leveraged Bitcoin ETF. Chief Executive Officer Michael Saylor, one of the biggest evangelists for the digital coin, began buying it for his company in 2020, and it held 252,220 bitcoins as of the end of the third quarter.

Michael Saylor's wealth has soared on his aggressive bitcoin strategy. He's said he sees the price of bitcoin hitting $13 million by 2045.

The architect of the company’s audacious Bitcoin-hoarding strategy explains why he calls the crypto “a flow of money from the 20th century to the 21st century.”
