Which coin has more potential, what do you think?
More potential for what? Economic growth? Or Usability? Or something else, as many people in the forum I will not invest my money in ripple I dont like the fact that is a centralized system, litecoin in the other hand was more a copy of bitcoin, but with the addition of segwit then the network is going to be even faster than before and that could really be a great way to improve the usage of litecoin as people try to get around the slowness of bitcoin.
