It always becomes shady when a unknown "company" like this one starts posting pictures of another known company like Bitmain. Without providing proof of their claims they are trying to attract buyers for the contracts. This is robbery at its best which is easy to do in the internet.

Reviews are always biased so no use reading and making an opinion from the. Any cloud mining site is going to be scam in the long term whether it be a long drawn con or a short con. If you are going to invest in it then its your choice but I would steer clear of this one or any other "cloud mining".
