Bitcoin ($BTC) is the world's first decentralized digital currency, created by a developer using the pseudonym 'Satoshi Nakamoto' in 2009. It is based on blockchain technology, ensuring transaction transparency and security through distributed ledgering. The total supply of Bitcoin is capped at 21 million coins, possessing anti-inflation properties, and is dubbed 'digital gold'. Bitcoin does not rely on traditional financial systems and is issued through a 'mining' mechanism, attracting a large number of miners and investors to participate. In recent years, with institutional funds entering the market and changes in the macroeconomic environment, Bitcoin has gradually become a store of value and a safe-haven asset. However, its price is highly volatile, and it also faces challenges from regulatory policies and market uncertainties.
