I am very satisfied with Hitbtc, good volume and many tokens come there first. Also nice people at support, they solved a missing deposit for me in a day recently. Had one in december taking weeks but then it was so stuffed with new customers that the site broke down each day before they upgraded servers.

I'd be happy if you used my reflink, I posted it in https://steemit.com/exchange/@thedolphin/nice-new-function-at-hitbtc-exchange today :)
