Bitcoin, created in 2009 by the mysterious Satoshi Nakamoto, is the first decentralized digital currency. It has a fixed supply of 21 million coins, making it deflationary by design. The first real-world Bitcoin transaction bought two pizzas for 10,000 BTC in 2010—now worth millions.
Bitcoin mining consumes more energy than some countries. Its blockchain technology ensures transparency and security without needing a central authority. Despite skepticism, it’s considered “digital gold” and has sparked a global movement toward financial independence. No one knows who Satoshi is—making Bitcoin not just currency, but a cryptographic legend.
