OK. I can relate to a lot of victims here and i have personally lost $84,000 (you are reading it correctly) worth of BTC in the month of August, 2017.
I have been going back and forth with their representing lawyer (Joseph Cutler of Perkins Coie LLP).

I strongly suggest that since we have so many victims of BITTREX scam we should reach out to CFPB (consumer financial protection bureau). This agency goes by volume irrespective of the monetary value.

THis is my second life as the first scam where i lost all the funds almost gave me a heart attack.

And all could get back from BITTREX is we are sorry that your funds were lost and they cannot protect against such hacking attacks.
