Normal crypto-coins are a code-based resource designed to be employed as a medium of trade. Additional crypto-coins are found by mining. Any person can get involved by using their a computer. Mining requires a great deal of time and electrical power, however. A high-powered machine is also required, to do this profitably. However, Ripple is a centralised coin, which is unmineable. A limited amount of units were generated by the organisation and this amount will never be exceeded.
