$BTC Bitcoin (BTC) is the king of crypto, the OG that started it all in 2009. With a fixed supply of 21 million, it's deflationary by nature and often called "digital gold." Bitcoin runs on a decentralized network powered by proof-of-work, making it secure and censorship-resistant. It's used as a hedge against inflation, a store of value, and sometimes even for daily transactions. BTC's impact goes beyond finance—it's a global movement toward financial freedom. From El Salvador to ETFs on Wall Street, Bitcoin continues to break barriers. Whether you're in for tech or gains, BTC is the heartbeat of crypto.
