An investment in Ripple is only profitable for a short term. The current xrp situation on the market confirms that it is a typical pump and dump coin. And this is associated with potential large losses. Buying xrp should be able to count on potential large losses. This is not a long term investment.
I think a short or long investment depends on when the investor buys it. If someone buys it at a high price, and then the market goes down, it will take a long time for that investment to make a profit.
I do not think investing in xrp on a long term is a good idea. It is better to wait for a good moment and invest in a short term and make profits. The last increase in xrp prices only confirms this.
