Normal crypto is a digital asset created to be used as a medium of exchange. New crypto-coins may be added via mining. Everyone is able to get involved if they have a a computer. Mining requires a great deal of time and electricity, though. A high-powered computer is also required, to do this successfully. However, XRP is a centralised coin, which can't be mined. A finite supply of tokens were created by the company and this amount will not be added to.
