Bitcoin (BTC) is a decentralized digital currency that operates without a central authority or bank. It was introduced in 2009 by an anonymous person or group using the name Satoshi Nakamoto. Bitcoin transactions are verified by network nodes through cryptography and recorded on a public ledger called the blockchain. It allows peer-to-peer transactions worldwide, offering a secure and transparent method of transferring value. Bitcoin has gained popularity as both a form of investment and a potential hedge against inflation. Its limited supply of 21 million coins contributes to its value, making it one of the most recognized cryptocurrencies globally.
