Bitcoin (BTC) is known as the first open-source digital cryptocurrency that was developed and launched by a group of unknown independent programmers called Satoshi Nakamoto in 2008. Bitcoin does not have any centralized server used for its issuance, transactions, and storage, as it utilizes a public distributed network database technology called blockchain, which requires an electronic signature and is backed by a proof-of-work protocol to provide security and legitimacy for monetary transactions. The issuance of Bitcoin is carried out by users with mining capabilities and is limited to 21 million coins. Currently, Bitcoin's market capitalization exceeds $138 billion and it is the most popular type of digital currency. The buying and selling of cryptocurrencies is available through special platforms of Bitcoin exchanges or ATMs.
