Well it is a HYIP and you need to bear that in mind, but as of the day of writing of this article the site pays. You should NEVER invest amount of money which you are not able to loose. I cannot guarantee you that you will make profits, I personally did. ROI is 10% so its 10 days till you're good. But still @shaw1 a valid point.
And as you talk about legitimate cloud mining I strongly recommend VOZEX. They even have an online cam from the servers. Here's a link http://vozex.io/?ref=7hFutf
Have a nice day
