$BTC
Bitcoin (BTC) is a decentralized digital currency that operates without a central authority like a bank or government. Launched in 2009 by an anonymous entity known as Satoshi Nakamoto, Bitcoin runs on blockchain technology, a secure and transparent ledger that records all transactions. It is mined using a process called proof-of-work, where powerful computers solve complex mathematical problems. Bitcoin is often seen as "digital gold" due to its limited supply of 21 million coins, making it a popular investment and store of value. It is widely used for transactions, trading, and hedging against inflation.
