Bitcoin, often referred to as the king of cryptocurrencies, is a decentralized digital currency that operates on a peer-to-peer network without the need for intermediaries such as banks or governments. It was introduced in 2008 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto, who outlined the concept in a whitepaper titled "Bitcoin: A Peer-to-Peer Electronic Cash System." Bitcoin transactions are recorded on a public ledger called the blockchain, which ensures transparency and immutability. Unlike traditional fiat currencies, which are issued and regulated by central authorities, Bitcoin is created through a process called mining, where participants use powerful computers to solve complex mathematical puzzles and verify transactions. This process not only creates new bitcoins but also secures the network against fraudulent activities. With its finite supply capped at 21 million coins, Bitcoin is often seen as a hedge against inflation and a store of value akin to digital gold. Its decentralized nature, limited supply, and growing adoption have propelled Bitcoin to become one of the most valuable assets in the world, with a vibrant ecosystem of users, developers, and businesses contributing to its ongoing success.
