Although indeed the price is currently goes up we cannot really say that they can sustain that. I guess supporting a losing candidate didn't their coin much and we see XRP is having good rally. But people should think about that nothing will goes up so if they don't want to be left behind when there's a dump happened better if they would sale their coins early especially if they are ready to take their profits.
So far didn't think about buying XRP at the moment since there are things are bit off to me. I'd rather focus on bitcoin at the moment that buying XRP then hold it since we cannot assure that everything will always go according to what they like to happen in this coin.
