My account is still working flawlessly but there have been lot of red flags lately that makes me scared. Delisting Bitshares, hack rumours after alt coin dump, raised withdrawal fees on ether tokens and now disabled accounts.

Arbitrary lockings of accounts with stored funds is the worst thing that can happen to the credibility of a financial company. It makes it no better than some shady casino that allow deposits without verifications but have a huge processes for cashing out. Bittrex really have to show some serious explanation about this if they want to keep their reputation.
