I think we will see this xChainge in action as service provider because soft cap of 10k etherum is not really high to get worried about. I am saying because concept and features described here gives signals that minimum is possible though hard cap seems bit really hard.
I am totally agree with you. Low hard cap its always good for investors because with low market cap project can easily make x2-x10 and more.
In case with xChainge their cap much less than in kyber, 0x and airswap and if dev team can makes ideas come true then they will be strong competitors for another exchanges
