Bitcoin ($BTC ) is the original cryptocurrency 🌍, launched in 2009 by the mysterious Satoshi Nakamoto. It operates on a decentralized network 🧠 using blockchain technology—think of it as a digital ledger that records every transaction transparently. With only 21 million coins ever to exist 🔒, scarcity drives its value over time. Often seen as "digital gold" 🪙, Bitcoin is used both as a store of value and a medium of exchange. It’s mined ⛏️ through a proof-of-work mechanism, which ensures security and trust without needing banks. $BTC has sparked a global revolution in finance—and it’s just getting started 🚀.
