There are alot of suspicious activities going on on most of these new exchanges, since the launch of trade mining it is a very difficult issue to know the amount of volume on these exchanges that are actually real, if I were you I won't trade there until I know my funds are safe on those exchanges
Often they take for free listings coins that have small teams but are still good coins with honest people. It's your only bet if you don't currently want to spend the money for the listing fee. Some will probably build up trust in time. You can get in and get out, and maybe reward them for listing your coin by doing a some trading there.
