Bittrex is very very upsetting and not satisfying for professional cryptocurrency exchanges.
I made about 100+ trades; then I'm surprised that my two-factor authentication suddenly stopped working and I get a nice email stating some garbage. The customer service emailed me saying that I have been sending too many emails to them. Well, it is my money, and I am losing a ton of money while I am not trading. And I can't get out of certain trades.
Nobody is getting back to me from customer support, and this is very disturbing. They also included in their email explaining that they are overwhelmed. Well get some people in there and solve the problems. I am actively looking for an alternative solution so I can leave Bittrex.
