$BTC Bitcoin (BTC) is a decentralized digital currency that operates without a central authority like a bank or government. It was introduced in 2009 by an anonymous person or group using the name Satoshi Nakamoto. Bitcoin is powered by blockchain technology, a transparent and secure public ledger that records all transactions. One of its main features is scarcity—only 21 million bitcoins will ever exist, making it a deflationary asset. This limited supply has led many to compare Bitcoin to gold, often calling it "digital gold."

Bitcoin allows peer-to-peer transactions across borders without intermediaries, making it a powerful tool for financial freedom, especially in countries with unstable currencies. Many investors see BTC as a hedge against inflation and a long-term store of value.
