Bitcoin is a digital currency started in 2009 that creates unique, non-duplicable electronic tokens using software (dubbed mining) with an asymptotic limit of creation of 21 million tokens, Bitcoin is a network run by the people, for the people. Because all transactions are encrypted and stored on a public record, the system is safe, transparent and doesn’t require banks or governments to function. Due to its limited supply, the currency is a good store of value too.
