Bitcoin (BTC) was the first distributed digital currency created in 2009. It was invented by Satoshi Satoshi based on open source software that allows users to conduct peer-to-peer transactions over the Internet. These transactions recorded in decentralized public ledgers. Bitcoin holds the largest market capitalization of all cryptocurrencies and is 19 times larger than Ethereum, which ranks second in the rankings.
The number of units is 21 million, of which 16 million are available. The upper limit ensures that inflation does not reduce its value.
When users allocate computer processing power to mining Bitcoin, they will receive transaction fees and newly created coins. Its units can be purchased or sold against other cryptocurrencies or fiat currencies, such as USD or EUR on multiple exchanges, like physical currency transactions. Its unit can also save or exchange goods or services. For example, TradingView accepts the Bitcoin payment annual plan and is a company that allows Bitcoin to purchase online products or services in multiple companies.
