$BTC

Bitcoin (BTC) is a decentralized digital currency that operates without a central authority, using blockchain technology to verify and record transactions. Introduced in 2009 by the pseudonymous creator Satoshi Nakamoto, Bitcoin allows peer-to-peer payments across the globe. Its supply is limited to 21 million coins, making it resistant to inflation. Bitcoin is mined through a process called proof-of-work, where powerful computers solve complex mathematical problems. It is praised for its transparency, security, and potential to disrupt traditional financial systems. However, it also faces criticism for energy consumption, price volatility, and use in illicit activities. Despite this, Bitcoin continues gaining global attention.
