Standard crypto-coins are a code-based resource designed to be used as an item of trade. units may be added via mining. Any person may do this if they have a a computer. Mining requires a great deal of hours and electrical power, though. A high-powered machine is also required, to mine profitably. Conversely, XRP is a centralised resource, which is unmineable. A finite amount of coins were made by the organisation and this limit will never be added to.
