$BTC Bitcoin (BTC) is a decentralized digital currency created in 2009 by an anonymous person or group under the pseudonym Satoshi Nakamoto. Unlike traditional currencies, Bitcoin operates without a central authority or government, relying on blockchain technology to record transactions securely. The currency is mined by solving complex mathematical problems, which ensures the integrity of the network. Bitcoin has gained significant popularity as both a store of value and a speculative asset. Its limited supply of 21 million coins creates scarcity, contributing to its value. Despite volatility and regulatory challenges, Bitcoin continues to influence the financial landscape worldwide.
