Standard crypto is a digital holding created to be employed as an item of trade. New units may be created by mining. Anyone can do this if they have a a device. Mining uses a great deal of time and electrical power, though. A high-powered machine is also vital, to mine profitably. On the other hand, Ripple is a centralised resource, which is unmineable. A limited amount of units were generated by the firm and this number will not be added to.
