Normal cryptocurrency is a code-based holding created to be used as an apparatus of trade. Additional units may be found by mining. Any person may do this if they've access to a computer. Mining requires a lot of hours and electrical power, though. A fast computer is also vital, to mine profitably. On the other hand, XRP is a centralised asset, which cannot be mined. A fixed amount of units were made by the organisation and this number will not be added to.
