I think UKG - Unikoingold is worthy of your investment. I've read that even shark Cuban invested millions dollars on this. We all know that where Cuban puts his money, everyone else follows. Seen a good growth since it was added on bittrex. It already has its platform for esports betting and it plans to release a mining rig with bonus rates on dedicated pools when you mine UKG coins. In fact, I already invested on this coin.

I already have my doubts on XRP since bloomberg released that news although someone had stored 3 billion XRP (part of the 125M$ from japan exchange).
NEO, as what they call Chinese ethereum has a good potential for profit I think.
