Normal crypto is a code-based asset built to be employed as an item of trade. New coins are created by mining. Everyone can get involved if they have a a device. Mining uses a large amount of time and electricity, though. A high-powered computer is also needed, to mine profitably. Conversely, Ripple is a centralised coin, which is unmineable. A fixed amount of units were generated by the firm and this number will not be added to.
