Is the first time I see this site and being cloud mining you should not invest your bitcoin in that site, Cloud mining is a waste of money and time, in the end you get a lot more profit if only you buy bitcoin and hold for some time
I did some research on google about this site and I just found this
Kamfai Liu, I assume this name belongs to the site owner and do not be fooled by it: "
CLOUD MINING OF THE NEW GENERATION "
