I cannot seem to get bittrex to work. I generated my API keys, go back into the CAT and every time I attempt to login I get a User Not Found message... anyone else having this issue with Bittrex?
Trex is working fine for me - did you enable trading on the API key and follow 2FA/verification procedures whilst setting it up?
Yes, I've used it in the past. I even generated my keys again just to be sure...
