Normal crypto is a code-based holding built to be used as an apparatus of trade. units are added by mining. Everyone is able to do this by using their a device. Mining requires a lot of time and electrical power, though. A high-powered machine is also needed, to mine effectively. On the other hand, Ripple is a centralised resource, which can't be mined. A fixed amount of tokens were generated by the organisation and this limit will not be exceeded.
