It's funny, I've had a Bittrex account and never used it. I actually wrote this on the 9th and less than 12 hours later they reopened registrations (figures, right?), requiring me to go back and edit, and create all new screenshots. I read a fair number of complaints about the new UI, but I love it and may begin using Bittrex now. I'm waiting to see if they've well and truly gotten their shit together though.
