Centralised cryptocurrency is a digital resource designed to be employed as a medium of exchange. New crypto-coins can be added via mining. Everyone is able to get involved by using their a device. 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 resource, which cannot be mined. A fixed amount of units were made by the firm and this limit will not be added to.
