Normal crypto is a digital resource designed to be used as an apparatus of trade. Additional crypto-coins may be found by mining. Any person can participate if they've access to a computer. Mining requires a great deal of time and electrical power, though. A high-powered machine is also vital, to do this profitably. However, XRP is a centralised asset, which is unmineable. A limited amount of units were generated by the company and this number will never be added to.
