To be honest with You guys, I've already transfered almost all my coins into other exchange and right now I'm just waiting for IGNIS and damn wallet update on cardano because from over 25 december there is still wallet disabled on cardano in bittrex which is so unbelievable !@#! So as soon as they will enable withdrawal on ADA, I will transfer it to other exchange. I'm disappointed about BITTREX.
Try this:
On Bittrex go to the Bittrex logo next to "markets". You'll get all three markets. Search ADA and you'll end up on ADA page where you can trade even though wallet is disabled. It's like a bug but I have been able to trade regardless of wallet maintenance. They should fix that
