Dragonex is an excellent exchange and gets better every day. I appreciate the strict security measures put in place - perhaps the best I have ever seen - low fees, a large variety of coins availabbe for trading (both old coins like eth, btc e. t. c and new coins like revain ,omg). The trading interface is functional enough to satisfy advanced marketers, but quite easy for those who are still learning. The consistency and dividend system is just a cherry on the top.
