Is Ripple XRP a Safe Investment?

Centralised cryptocurrency is a code-based holding designed to be used as an item of exchange. New units can be added through mining. Anyone is able to participate if they have a a computer. Mining requires a large amount of hours and electricity, however. A powerful machine is also required, to mine profitably. Conversely, XRP is a centralised coin, which can't be mined. A limited number of units were generated by the firm and this number will not be added to.
