$BTC Bitcoin (BTC) is a decentralized digital currency, the first and most prominent cryptocurrency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a peer-to-peer network utilizing blockchain technology, a public and immutable ledger that records all transactions. This distributed nature eliminates the need for central authorities like banks or governments, offering financial autonomy. Bitcoin's supply is capped at 21 million, making it a scarce asset often compared to digital gold. Its value is highly volatile, driven by market sentiment, adoption rates, and speculative trading. Despite price fluctuations, BTC continues to gain recognition as both an investment and a medium of exchange, impacting global financial systems.
