Is C-CEX any good? I've been with Bittrex for most of my trading (only a few weeks) but their display is shitfully slow, they have huge amounts of bot activity, displays aren't modal (i.e. select 1 Day on a chart, change charts and it's back to 30 min default) and I really don't like paying fees on incoming/outgoing transfers.

Honestly, how a company can make so many stupid mistakes and stay in business is anyone's guess. It's about as user-friendly as a Fidonet BBS.
