Normal crypto is a code-based resource built to work as a medium of trade. crypto-coins can be added via mining. Any person is able to do this if they have a a computer. Mining requires a great deal of hours and electricity, however. A high-powered computer is also needed, to do this effectively. However, XRP is a centralised asset, which can't be mined. A fixed amount of units were created by the company and this number will never be added to.
