Normal crypto-coins are a code-based holding built to work as an item of exchange. Additional units may be found via mining. Everyone may do this by using their a computer. Mining requires a large amount of hours and electricity, though. A powerful computer is also vital, to mine profitably. On the other hand, Ripple is a centralised coin, which cannot be mined. A fixed supply of tokens were made by the company and this amount will not be added to.
