$BTC
Bitcoin (BTC) is a decentralized digital currency created in 2009 by an anonymous person or group under the pseudonym Satoshi Nakamoto. It operates on blockchain technology, a public ledger that records all transactions securely and transparently. Bitcoin is free from government control or interference, relying instead on peer-to-peer transactions verified by network nodes through cryptography. Its limited supply of 21 million coins makes it a deflationary asset, often referred to as "digital gold." Bitcoin has become a popular investment and payment method, offering advantages like low transaction fees and fast transfers while revolutionizing global finance.
