$BTC

Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, introduced in 2009 by an anonymous creator known as Satoshi Nakamoto. It was designed to function as a decentralized digital currency, allowing people to send and receive money globally without needing banks or intermediaries. Transactions are verified through a secure, transparent system called the blockchain, where each transaction is permanently recorded and protected by cryptography.

One of Bitcoin's key features is its limited supply—only 21 million BTC will ever exist. This scarcity, combined with growing adoption, has helped drive its value over time. Bitcoin is often referred to as "digital gold", serving as a hedge against inflation and economic instability.

Today, BTC is used not just for transactions, but also as a store of value and investment asset. It has inspired an entire ecosystem of cryptocurrencies and continues to shape the future of finance.
