Cryptography, the process of protecting information by using codes, is used for the security of cryptocurrencies. It’s also used to control transactions and increase the supply. With this feature, cryptocurrencies have become self-governing and self-regulating. Digital money is free from the shackles and rules of traditional banks. This allows practically everyone to complete digital transactions without a third-party financial institution facilitating the process. By principle, the cryptocurrency model is a financial system designed by the people, for the people.
