The past few weeks PotCoin has been doing very good. Where as Ripple not as expected. I think PotCoin will rise in price even higher. As cannabis becomes more legal in many states the price will continue to go up.
Ripple has not been moving very much in price. In fact i am not a big fan of Ripple anyway but hear people mentioning it quite often. Maybe because of the big market cap.
In my opinion I rather invest in PotCoin then in Ripple at this point.
