I can't even remember when last I used bittrex as exchange again, unlike before there popularity has dropped drastically over the past years, I don't think this action will have such huge impact.
Last time I used them was before they shut down my account because I refused to do KYC.
Bittrex is one of the most corrupt exchanges. They will close your account if they want to and not allow you to withdraw your coins. They do what they want. Don't hold your coins there or you'll be sorry.
