Bitcoin (BTC) is a decentralized digital currency introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a peer-to-peer network using blockchain technology to ensure transparent and secure transactions without intermediaries. Bitcoin is mined through solving complex mathematical problems, and its supply is capped at 21 million coins, making it scarce. It’s often viewed as digital gold due to its store-of-value properties. $BTC can be used for payments, investments, or as a hedge against inflation. Its decentralized nature challenges traditional financial systems, promoting autonomy, censorship resistance, and innovation in the global economy.
