$BTC

BTC, or Bitcoin, is a decentralized digital currency that operates without a central authority, such as a government or bank. It was created in 2008 by an anonymous individual or group under the pseudonym Satoshi Nakamoto. Bitcoin transactions are secured using cryptography and recorded on a public ledger called the blockchain. Unlike traditional currencies, Bitcoin has a fixed supply limit of 21 million coins, which creates scarcity and, in theory, drives value. It is commonly used for peer-to-peer transactions, investments, and as a store of value, often referred to as "digital gold." Bitcoin has experienced significant volatility but has garnered global interest as a potential alternative to traditional financial systems.
