$BTC
Bitcoin (BTC) is a decentralized digital currency introduced in 2009 by an anonymous person or group using the name Satoshi Nakamoto. It operates without a central authority, using blockchain technology to verify transactions and maintain transparency. Bitcoin allows peer-to-peer transfers globally, offering a secure and irreversible method of payment. It is limited to a maximum supply of 21 million coins, which helps maintain its scarcity and value. Widely regarded as the first and most prominent cryptocurrency, Bitcoin has influenced the development of thousands of other digital assets and is increasingly being accepted for investment and payment purposes worldwide.
