you should better stay away from any type of cloud mining sites because all of them are shit ponzis. if you are so much interested in mining then why not buy a mining rig for yourself rather than investing in a company which promises so big return and tells itself a cloud mining company. i hope that you have understood what i want to say. also, that site is  created on 16 july 2016 which means that it is relatively new and no information about it on google and bitcointalk clearly means that no one knows about it and it is made just for the purpose of scamming some innocent noobs. btw, how did you come to know about that unknown site ?
