That's why the popularity of the bittrex will fall asap. There is a lot of problem with it. I've got the same problem. I got fucked around 5k caused by a slow response to the sell order.
I move to the binance. Polo and bittrex was same exchange site with a lot of problems. I retired from there.
Mate, I don't know about you, but I put 80% of life savings into crypto and it took forever just to bloody 2x them.
So to have 10k taken off that total is displeasing to say the least. Feeling quite shite, won't lie. Any words of wisdom? Other than locate your balls I suppose xD
