The website is down so i guess this is just another failed ICO or perhaps even a scam. It's a shame when these projects come and go, it makes it harder for investors to join in as they won't know which ones are good without extensive research.
That's not accessible from OP's link, you can use this link
https://www.daex.io/, or you could input directly on the browser "daex.io," Their website is fine.
I found their new Youtube video, a simple and easy to understand explanation of DAEX's concept. In case, read a whitepaper makes a headache, cause I felt it.
