#OnChainLendingSurge Bitcoin (BTC) is a decentralized digital currency introduced in 2009 by the pseudonymous Satoshi Nakamoto. It operates on blockchain technology, a transparent and secure ledger maintained by a global network of computers. Unlike traditional currencies, Bitcoin is not controlled by any central authority, offering financial freedom and resistance to censorship. Its supply is capped at 21 million coins, making it deflationary and often compared to digital gold. Transactions are validated through mining, which secures the network but is energy-intensive. Bitcoin has sparked global interest as a store of value, medium of exchange, and foundation for the broader cryptocurrency ecosystem.
