Once the EON main net goes live, any exchange will be able to list the coin. Bittrex, Polo, or any other exchange. We don't make any arrangements, but we also can't forbid anyone to list EON coins.
In case no exchange lists them, EON coins will be tradeable on the Exscudo Exchange after its launch in Autumn.
I understand your point of view but you had to contact exchange first without insisting then it is up to exchanges if they list EON or not. I think just waiting for exchanges to contact you is enough as EON need to reach at that level where listing it will be in interest of exchanges. I hope you understand my point what I mean to say with all this.
Yes, I see your point. We are building a competitor to other exchanges. I would rather say, an exchanges-killer.

This is why we follow this policy. We have already been contacted by a couple of exchanges, but we prefer to make no commitments.
Sounds awesome!=) I fill really good about your work, and that all us was a part of it=)
