Normal crypto-coins are a digital asset built to be used as an apparatus of exchange. New units can be found through mining. Anyone may do this if they've access to a device. Mining uses a lot of hours and electrical power, though. A high-powered computer is also vital, to mine profitably. However, Ripple is a centralised coin, which is unmineable. A finite number of coins were generated by the organisation and this number will never be added to.
