look, don't just take my word for it. Do your due diligence. You can find a thread in this forum, as well as on Bitcointalk.
Genesis contracts so far are very unlikely to reach ROI. The payouts are also strangely linear, and do not follow the same fluctuations as a hashnest contract or home mining.
This, plus the repeated screwing over of their customers makes me very wary of them these days.
