As long as your account verification is all fine and set up, there is nothing to be worried about. Problem with Bittrex is that they are so badly lacking staff to work through their support tickets, that it in some cases takes a couple of weeks to see them respond back to you, which is completely unacceptable, but unfortunately the reality that no one beside Bittrex can do anything about. It has gotten so bad, that they at this point not even accept new registrants anymore, which is something they can only blame themselves for - their lacking will to upgrade (i.e spend money) at the moment the growth was just mildly starting to pick up, is now holding them back and of course the users who are suffering from their incompetence.
