It's a professional HFT exchange for digital assets targeting the really large customers like Hedge funds and governments. It's almost ready for launch, and they want to make some buzz. You can support it and get your name on their dedicated backers thank you page while receiving free trade fees. It's not because they need the money, but because they want to spread the word. So please do.
Here is the support page on startjoin:https://www.startjoin.com/DAXP
An their web page: http://www.blockex.com/about/ - as you can see there are professinal bankers, and John Matonis (Bitcoin foundation leader) on the list of Advisors.
What do you guys think? I think this might prove to be a really, really important development.
