I was also a huge fan of Bittrex. Well, until now I am still using Bittrex. In fact, my Bittrex wallet still contains the major coins that I am holding. Bittrex used to have one of the longest list of coins. That is one of the reasons why I chose Bittrex. I can easily do trading because of the wide array of choices. However, I also admit that Bittrex has somehow gone down. They started to de-list coins, went through some rounds of glitches, stopped accepting new accounts, and went hard on their listing deals for new coins.
