Bitcoin (BTC) is the world's first cryptocurrency, launched by Satoshi Nakamoto in 2009. It is based on blockchain technology and uses a decentralized peer-to-peer network without a central issuing authority. Bitcoin is generated through a 'mining' mechanism, with a total supply capped at 21 million coins, which is considered to have anti-inflation characteristics. As 'digital gold', Bitcoin is not only a store of value but also a globally accepted means of payment. In recent years, with the entry of institutional investors and increasing macroeconomic uncertainty, Bitcoin's market influence has continued to rise. However, Bitcoin's price is highly volatile and it faces challenges such as regulatory scrutiny and environmental controversies.
