Don't use bittrex.

I made a deposit of aprox 10K USD in crypto and because of their technical problems the deposit didn't get credited as usual.

Now they tell me that they have to manually check it and that it could take a month or more and this if it finally gets credited, maybe I "lose" my coins, they don't assure me that it will be credited even having blockchain tx id proof.WTF

This is unacceptable, avoid this exchange at all costs.
