$BTC

#BTC is the widely used hashtag for Bitcoin, the first and most well-known cryptocurrency. Launched in 2009 by the pseudonymous Satoshi Nakamoto, Bitcoin operates on a decentralized blockchain, allowing peer-to-peer transactions without intermediaries. It has a fixed supply of 21 million coins, making it deflationary by design. #BTC is often used on social media to track price updates, share news, or discuss trading strategies. Bitcoin is considered both a digital currency and a store of value, often dubbed "digital gold." Its influence shapes the broader crypto market, and it remains a benchmark for cryptocurrency performance and innovation.
