Almost 4 months without a solution...
What's your concern with bittrex? I'm not able to read all the messages here but if that's not helping you try to send them another ticket. There are a lot of tickets that has been sent and for sure yours was buried by another ticket from other traders who addressed their complain to them.
bittrex basically stole thousands of users funds without warning them , they suddenly started to stop supporting some countries that the US forbids trading with
while this rule of US has existed for a couple of years , Bittrex decided to stop the traders from these countries without warning and they haven't paid the user their hard earned money
there are tons of problems even for residents of other countries , basically everyone who is trusting bittrex after this is throwing the money away
That's why I stopped them too when they started to ask for some identifications as I find it quite doubtful if there's a website offshore that's asking for my identity. And I thought that sending them another ticket will help the concerns but it looks like they are being left behind with some new exchanges who are making some noise with their customer service.
