Uro is going higher regardless. You'd be a fool to sell right now. #UROCOIN is getting a ton of attention and is forming a community with a rare amount of coins. Only 300K have been mined so far and has a backing of a commodity.
Hopefully you're right but this is why I say that it's bad to go to Mintpal in general, but especially bad if it's too early. It just destroys any kind of momentum and to be honest they seem to relish the disproportionate power they hold over cryptocurrency. Lets just hope they get replaced by Bittrex soon.
If and when URO is being successfully traded for urea then that won't matter. URO will be in a class by itself.
