I have basic verification with the permitted withdraw in 0.4 BTC. For me that's enough. I am going to pass enhanced verification , but i dont think thats gonna be problem, my friends passed that during 2 hours. Some of them have the problem and their accounts were deactivated - the sounded reason - participation in the PAMP of coins. dont take a part in them or you will be banned by bittrex.
Dont trust bittrex , they will turn your account to New member or lock your account for no reason to force you to provide them all documents.
I advice you to withdraw your coins asap from this crook exchange and trade in other exchanges like binance.
