I don't know if you are updated on the recent happenings on cryptopia. Have you seen the issues? for you to say that cryptopia isn't prone on such problems? They aren't and just like other users of such exchange I did experience some delays too which isn't really surprising. Each exchanges are now facing off delays that's why for op seeking out exchangers would be a tough job testing out each one of them but rest assured delays would be surely experience along the way.
