I think i got hacked the same way (The IP Address of the hacker was also from Russia), it is weird how Bittrex won't prompt an email confirmation to the user when the IP address is very off (I also live very far away from Russia)
Hello tachypknea
I also don't understand that. I always logged in from the same country, so it's strage that they/the security system did nothing when suddenly in ip from Russia logged in.
Did you already get an answer from the support?
