Bitcoin (BTC) is a decentralized digital currency that allows peer-to-peer transactions without the need for intermediaries like banks. It was created in 2009 by an anonymous person or group known as Satoshi Nakamoto. Bitcoin operates on a technology called blockchain, which ensures transparency and security by recording every transaction across a distributed network. As a limited supply asset with a cap of 21 million coins, Bitcoin is often viewed as a store of value, similar to gold. It has gained popularity as both an investment and a means of transferring money across borders.
