Bitcoin Whitepaper Turns 18: How Satoshi Nakamoto’s Vision Became a $1.55 Trillion Asset

Bitcoin marks 18 years since Satoshi Nakamoto published its nine-page whitepaper on October 31, 2008. More than 95% of Bitcoin's 21 million supply has been mined, with the 20 millionth BTC reached in March 2026. U.S. spot Bitcoin ETFs hold approximately 1.28 million BTC, representing 6.36% of circulating supply. Bitcoin’s nine-page whitepaper marks its 18th anniversary today, celebrating a milestone for a network that began with a simple idea, allowing people to send money without banks or financial institutions.
