What Kraken (in my opinion one of the best exchanges of all time) does is completely normal, they have to be legally covered for being in the United States. Nothing will happen to XRP, in fact, if we look at its price we will see that in the last 24 hours it has risen 12.32%. We can continue buying and selling and that is what many investors are taking advantage of, they accumulate all they can for when it comes back up.
