$BTC

Bitcoin (BTC) is a decentralized digital currency introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. Unlike traditional currencies, it operates without a central authority or bank, relying instead on blockchain technology—a public ledger containing all transaction data. Bitcoin can be used for peer-to-peer transactions, stored as an investment, or exchanged for goods and services. Its limited supply of 21 million coins adds to its appeal as "digital gold." Bitcoin’s price is highly volatile, influenced by market demand, regulation, and investor sentiment. Despite controversies over energy use and scalability, Bitcoin remains the most widely recognized and valuable cryptocurrency globally.
