Normal crypto is a code-based holding designed to work as a medium of exchange. Additional units can be created via mining. Everyone is able to do this by using their a computer. Mining requires a large amount of hours and electrical energy, though. A fast machine is also vital, to do this profitably. Conversely, Ripple is a centralised asset, which is unmineable. A limited number of tokens were created by the company and this amount will never be added to.
