Bitcoin is the first decentralized digital currency based on blockchain technology. It was created in 2009 by an anonymous developer or group under the pseudonym Satoshi Nakamoto. One of the key features of Bitcoin is its limited supply – only 21 million coins will ever be issued, making it a scarce asset. Bitcoin allows financial transactions to be made directly between users without the involvement of banks or other intermediaries, making it a fast and relatively cheap way to transfer money. Despite the high volatility of its exchange rate, Bitcoin has become a popular means of investment and is actively used both as digital gold and for real payments.
