Normal cryptocurrency is a digital holding built to be employed as an apparatus of exchange. Additional units can be added through mining. Any person is able to participate if they've access to a device. Mining uses a lot of hours and electrical power, however. A high-powered computer is also vital, to do this profitably. Conversely, Ripple is a centralised coin, which can't be mined. A limited amount of tokens were made by the firm and this number will not be added to.
