$TRX Bitcoin (BTC) is the first decentralized digital currency, created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. It operates on a peer-to-peer network without the need for intermediaries like banks. Transactions are verified by network nodes through cryptography and recorded on a public ledger called the blockchain. Bitcoin has a fixed supply of 21 million coins, making it deflationary in nature. It is widely used as a store of value and is often referred to as "digital gold." Bitcoin’s price is highly volatile and influenced by demand, adoption, market sentiment, and regulatory developments.
