I think it's great we have new professional exchanges opening by active members of the community.
Personally I love Kraken. It's my go to exchange for moving fiat in/out. They have spoiled me rotten. Now I get nervous if SEPA € transfers take more than one day, or if their support doesn't solve my ticket in a couple of hours. Also it's great that they actively monitor their thread on the forum and respond to questions.
No matter what issues an exchange has, good and responsive support is key.
So for me, this is a baseline you have to consider.
I'd love to move my altcoin trading over to you, cause Cryptsy likes to shut down for a day a few times a year, and they always sugar coat their issues. Something I really don't care for...
I'll also consider you when you get fiat pairs ready, and support SEPA thru an EU bank. Hint: Fidor is awesome and very crypocurrency friendly
But you probably know that already.
Can't wait to test this out
