SCAM. A classic one. After you 'mine free' for some time, you attempt to withdraw, and then they ask you to 're-invest' first. In other words, 'send us your money, and if you see us again, we'll send you our regards. Stay away. If they let me withdraw first, I will change my review, but I don't thing they will do that. Apparently, all the positive reviews here are either by naive, innocent people, or their own and the reviews are fake. Smart asses..
