Standard cryptocurrency is a code-based resource built to be used as a medium of trade. Additional crypto-coins are created by mining. Anyone can do this by using their a computer. Mining uses a great deal of time and electrical power, however. A high-powered computer is also needed, to mine successfully. On the other hand, Ripple is a centralised coin, which is unmineable. A limited number of coins were made by the firm and this amount will not be added to.
