Bitcoin (BTC) is the first and largest cryptocurrency, created in 2009 by an anonymous person or group under the pseudonym Satoshi Nakamoto. It operates on a decentralized peer‑to‑peer network called the blockchain, allowing secure and transparent digital transactions. Bitcoin has a fixed supply of 21 million coins, making it a deflationary digital currency. Its value is driven by scarcity, adoption, and trust in its protocol, making it a popular investment and a hedge against traditional market fluctuations. Today, Bitcoin is seen as both a revolutionary technology and a “digital gold” in the global financial landscape, reshaping how people think about money and value.
