This is a scam until:
Proof of contracts are posted,
Proof of team are posted
Proof of chip are posted, (die shots, layout etc)
Until then I see no reason why anyone with a brain is putting their money into xcrowd. Then again there are a lot of people on this forums without brains.
I guess you should change 'no brains' with 'risktakers'. I am sure early Bitcoin adopters were called 'brainless' by many people.
But yes, some proof would ofcourse be good.
