Bitcoin (CRYPTO: BTC) is the world's largest cryptocurrency. It has a market capitalization of $1.8 trillion as of this writing, representing more than half of the total value of all coins and tokens in circulation across the industry, which currently stands at $2.9 trillion. MicroStrategy (NASDAQ: MSTR) co-founder Michael Saylor thinks there is still substantial upside ahead, because he predicts Bitcoin will reshape the entire financial system thanks to its decentralized nature, its capped supply, and its secure system of record called the blockchain.
