I'm finding Mercatox to be a rather enjoyable exchange to use. Not too cluttered, easy to navigate, not overly complicated. Processing seems to be fairly quick as well. What does everyone else think about them?
It's OK, though it has some glitches. Sometimes I get the impression I'm not seeing all the orders and they don't necessarily fill in a logical order. For the first time, today I have a DNotes withdrawal that has been stuck for hours. Support has been responsive, though haven't yet resolved the issue. I'm also waiting ten days now to get verified so I can withdraw more than 0.5 BTC every 24 hours.
Other than that, it's fine.
I dream of having DNotes listed on Bittrex, as I think that is my favorite exchange to work with.
I do like Mercatox as well, my dealings with their support and administrative teams has been fantastic so far, and that is my top metric for judging an exchange as well as their professionalism. I'd like to see market depth and some performance improvements, as well as their private API developed. That would put them on par with some of the largest exchanges.
