$BTC
$BTC refers to Bitcoin, the first and most well-known cryptocurrency, created by an anonymous person or group known as Satoshi Nakamoto in 2009. It operates on a decentralized peer-to-peer network using blockchain technology to enable secure and transparent transactions without intermediaries. Bitcoin is often regarded as "digital gold" due to its limited supply of 21 million coins and its role as a store of value. It is used for various purposes, including investment, online payments, and as a hedge against inflation. Price volatility and regulatory concerns remain challenges, but Bitcoin's influence on the crypto market is undeniable.
