Well, not a scam, but a ponzi. First people in profit, the last ones in hold the bags.

So after about 3 hours they only sold about 730,000 GRX tokens out of 12,000,000 available for the ico. Considering they previously sold 7,500,000 tokens to the so called strategic investors and pre-sale at deep discounts, I can see why people are not jumping in.

I'll keep an eye on the sale, but I'll probably skip this one.
