$BTC is the first decentralized digital currency based on blockchain technology, created by the anonymous developer Satoshi Nakamoto in 2009. Its core concept is to achieve peer-to-peer transactions without the intervention of banks or governments through cryptography and distributed ledger technology. The total supply of Bitcoin is capped at 21 million coins, gradually released through a 'mining' mechanism (computational power competition to verify transactions), which possesses anti-inflation characteristics.

As the pioneer of cryptocurrencies, BTC has broken the monopoly of traditional financial systems over currency issuance, empowering users with asset autonomy. Its blockchain network is open and transparent, with all transaction records being verifiable and immutable, ensuring security. Despite significant price volatility, BTC is gradually recognized as 'digital gold', becoming an important store of value against the devaluation of fiat currencies.

The application scenarios of BTC have expanded from early purchases of pizza (such as the 2010 'Bitcoin Pizza Day') to areas like cross-border payments, smart contracts, and investments, promoting the global adoption of blockchain technology. Its decentralized philosophy and technological innovation have profoundly influenced finance, technology, and even social governance models, becoming a symbolic representation of the digital economy era.
