I have never had this issue on bittrex. But the real question is why is your Crypto on coinbase. I buy from them and immediately transfer to Exodus where I can then safely determine where it should go. If your tactic is to sell as a dump occurs try Exodus, in wallet shapeshift. This way you can just change Crypto vs bailing. This tactic will only allow change between Crypto, coinbase still had the benefit of sending back to your bank.
