$BTC Bitcoin ($BTC) is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous developer Satoshi Nakamoto. It operates on a decentralized peer-to-peer network using blockchain technology, allowing users to send and receive digital currency without relying on a central authority like a bank. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins, making it scarce and potentially valuable over time. Transactions are verified by miners using a consensus mechanism called Proof of Work, ensuring the integrity and security of the network. Bitcoin has gained global attention as both a store of value and a medium of exchange. It is highly volatile, often influenced by market sentiment, regulation, and adoption trends. Today, Bitcoin represents a major innovation in finance and digital ownership.
