Standard crypto-coins are a code-based resource designed to be employed as a medium of trade. New units are found by mining. Anyone can do this if they have a a computer. Mining requires a great deal of hours and electrical energy, though. A high-powered computer is also vital, to do this successfully. However, XRP is a centralised coin, which can't be mined. A limited supply of coins were created by the company and this amount will never be added to.
