I follow Unify since the creation but i think that its too early to try cex.io. It'll be very hard to get list at this exchange right now, since neither litecoin is listed yet... we must focus on bittrex, c-cex, binance and other exchanges firstly
I don't think it's going to be extremely hard. We've gotten their attention. CEX.IO told us that if we get enough votes they'll list us. So all we have to do is get as many votes as we can.
