Normal crypto-coins are a digital holding created to be employed as an item of trade. crypto-coins are added via mining. Anyone is able to participate if they've access to a computer. Mining requires a lot of time and electricity, though. A fast computer is also needed, to do this effectively. On the other hand, Ripple is a centralised coin, which cannot be mined. A limited number of units were created by the firm and this number will never be exceeded.
