They mostly seem to be on cryptopia, the problem is this is a small exchange. If you had say 3 million coins and it hit $0.01 I'm wondering if they would have the money to pay you out. There is a 5k daily withdrawal limit so who knows.
Thanks for the comment.
Yeah I don't know about cryptopia, they seam a bit strange, but maybe I just misunderstood what they are trying to do down there...
