#VietnamCryptoPolicy Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous person or group using the name Satoshi Nakamoto. It operates on a decentralized peer-to-peer network using blockchain technology, allowing secure and transparent transactions without a central authority. Bitcoin is mined through a process called proof-of-work, where powerful computers solve complex mathematical problems. It has a limited supply of 21 million coins, which adds to its scarcity and value. Bitcoin is widely used for investment, trading, and as a store of value, often referred to as "digital gold." Its price is highly volatile and market-driven.
