$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, launched in 2009 by the mysterious creator Satoshi Nakamoto. It operates on a decentralized blockchain network, meaning it’s not controlled by any government or bank. Bitcoin allows peer-to-peer transactions across borders with low fees and strong security. Its limited supply of 21 million coins makes it a digital store of value, often compared to gold. Over the years, BTC has gained massive popularity as both an investment and a means of payment. Despite price volatility, Bitcoin continues to shape the future of finance, inspiring innovation in blockchain technology and changing how we think about money.
