Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by the mysterious figure Satoshi Nakamoto. It introduced a decentralized digital currency system that operates without a central authority. Using blockchain technology, Bitcoin allows peer-to-peer transactions that are secure, transparent, and irreversible. Its limited supply—capped at 21 million coins—makes it a deflationary asset, often referred to as “digital gold.” Bitcoin has gained global attention as both an investment and a hedge against inflation. Despite price volatility and regulatory scrutiny, it remains the leading cryptocurrency by market value. Bitcoin has not only redefined money but also inspired an entire ecosystem of digital innovation.
