Friday marks the 16th anniversary of Bitcoin, the world's first cryptocurrency. Created by the pseudonymous Satoshi Nakamoto on January 3, 2009, Bitcoin has evolved from a niche experiment to the seventh most valuable asset globally, boasting a market cap nearing $2 trillion. This digital currency has minted thousands of millionaires, inspired over 10,000 other cryptocurrencies, and spawned an entire industry of exchanges, wallets, and trading apps.
The Origins of Bitcoin and Cryptocurrency
Bitcoin emerged as a response to the 2008 financial crisis. Its genesis block contained a headline from The Times: "Chancellor on brink of second bailout for banks." Nakamoto's whitepaper described Bitcoin as a "peer-to-peer electronic cash system" powered by blockchain technology—a decentralized, tamper-proof ledger recording all transactions.
Key features of Bitcoin:
✔ Decentralized: No banks or governments control its supply.
✔ Borderless: Requires only an internet connection for global transactions.
✔ Transparent: Public blockchain ensures accountability.
Initially adopted by dark web users, Bitcoin gradually gained mainstream traction, shedding its rebellious reputation.
Cryptocurrency Goes Mainstream
Bitcoin's meteoric rise—from under $20,000 to over $100,000 in 18 months—was fueled by institutional interest. In 2024, the SEC approved the first Bitcoin spot ETF, unlocking billions in institutional investment. By July, Ethereum ETFs followed, further legitimizing crypto.
Political endorsements also played a role. Donald Trump, the first pro-crypto U.S. presidential candidate, pledged to make America the "Bitcoin superpower of the world", nominating a crypto-friendly SEC chair and proposing a Bitcoin strategic reserve.
