Last 4 days XRP has pumped over 100%, if you have XRP before, you should sell now to get profits. You should not buy XRP now because it has increased too much, i think it's very hard to increase more, buy XRP now is risky. Do not FOMO!
Some guy said the same at +50%...
Well it's quite reasonable to caution people from buying now. Having doubled in value is quite tempting to take profits out for many holders. It can go to a correction phase anytime now. Same as what happened with btc last year.
