What is Bitcoin (BTC)?
BitcoinBitcoin is the first and largest cryptocurrency, created in 2009 by Satoshi Nakamoto. It operates on a decentralized peer-to-peer network with a fixed supply of 21 million coins.
Full Explanation

Bitcoin transactions are recorded on a public ledger called the blockchain, secured through a process called proof-of-work mining. Its total supply is capped at 21 million coins, making it deflationary by design. Bitcoin is often called "digital gold" due to its store-of-value properties.
