dude don't waste your time and your money to that site, most of the cloud mining is turn into scam after a month. they always promise lot of money and big profit but it does not real. after you invest to their site they hit you and run..
The problem isn't really those scam sites shutting down after just a month. The problem is that obvious schemes such as genesis mining continue to pay out their users due to the idiots investing their money in that service.
People, as dumb as they are, think that when a cloud mining service pays their users out, it by default is legitimate. This delusional way of thinking is the reason people continue to invest in these schemes.
Another major factor is that people even make the mistake to re-invest their earnings, and that's when the cloud mining service has got the better of you ~ re-investing your earnings means that you start from scratch again.
