Bitcoin is a decentralized digital currency that utilizes cryptography for secure financial transactions. It was created in 2009 by an anonymous individual or group known as Satoshi Nakamoto. Bitcoin operates on a peer-to-peer network, which means that there is no central authority or financial institution controlling it. Instead, transactions are recorded on a public ledger called the blockchain. This decentralized structure allows for anonymity and greater security, as the ledger is distributed across a network of computers rather than being stored in a single location. In order to participate in the Bitcoin network, users must install a wallet on their computer or mobile device, which allows them to send and receive bitcoins and track their balance. Bitcoin has gained significant popularity and recognition, although it is still considered a risky and volatile investment due to its lack of regulation and potential for fraud.

Bitcoin is a decentralized digital currency that operates on a peer-to-peer network without a central authority like banks or governments. Created in 2009 by an anonymous person or group known as Satoshi Nakamoto, it uses blockchain technology to ensure secure and transparent transactions.

The blockchain is a public ledger where all Bitcoin transactions are recorded and verified by miners using computational power to solve complex mathematical problems. This process, called mining, also introduces new Bitcoins into circulation.

Bitcoin is limited to 21 million coins, making it scarce and often compared to digital gold. It is stored in digital wallets and can be sent globally with low fees. Bitcoin's value is driven by supply, demand, and market sentiment.
