It was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. The currency is designed to be a decentralized alternative to traditional fiat currency, with transactions recorded on a public ledger called the blockchain. One of the key features of Bitcoin is its scarcity. There is a finite supply of 21 million bitcoins that can be mined, with roughly 18.7 million currently in circulation. This scarcity, combined with the growing acceptance of Bitcoin as a means of payment, has led to its value increasing significantly over the years.Another important aspect of Bitcoin is its decentralization. Unlike traditional currencies, which are controlled by governments or central banks, Bitcoin is not controlled by any single entity. Instead, it is maintained by a network of users and miners who work together to validate transactions and keep the blockchain secure. This decentralization is what makes Bitcoin resistant to censorship and manipulation.
