#DeFiGetsGraded Bitcoin (BTC) is the first and most well-known cryptocurrency, launched in 2009 by the anonymous creator Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, which records all transactions securely and transparently without a central authority. BTC has a fixed supply of 21 million coins, making it deflationary by design. It’s used for payments, investment, and as a store of value, often called “digital gold.” Mining secures the network through a proof-of-work system. Bitcoin’s price is highly volatile, influenced by market demand, adoption, regulation, and macroeconomic factors. It’s accessible globally and enables borderless transactions, appealing to those seeking financial freedom, though it faces scalability, environmental, and regulatory challenges.
