Avoid storing your funds in exchange. Third party wallet may risk your funds anytime. You have no assurance that you will get your money back when there are hacking incidents happen. The best thing you can do to secure your funds is to put it in a hard wallet. Bittrex is a good exchange but anytime, our funds is on risk. We can't blame them if there are incidents that happen to their exchange because they have no control at all. KYC process has been made difficulties for crypto users and even I will quit in an exchange that demands my identity. Because KYC for me is risking my identity.
