$BTC Bitcoin is a decentralized digital currency based on blockchain technology, created by Satoshi Nakamoto in 2009. It is generated through a mining mechanism, with a total supply limited to 21 million coins, and features such as anonymity and convenient cross-border circulation. Bitcoin prices are highly volatile, influenced by market supply and demand, regulatory policies, macroeconomic factors, and more. Due to its decentralized nature and anti-inflation properties, it is viewed by some investors as a safe-haven asset and a store of value; however, it also faces controversy due to its lack of regulation, frequent use in illegal transactions, and high energy consumption, leading to varying attitudes from different countries.
