Are you just pretending to be this dumb?

XBTMine is not a 'cloud mining' operation, it is a Ponzi-based scam. It will steal money from later users to pay earlier users until, inevitably, it doesn't have enough new users depositing the funds needed to cover what they have to pay out and it will collapse. Not before the OP has stolen as much as he can, of course.

All Ponzi scams *have* to pay out at first because the moment they stop then people panic and try to withdraw their funds en masse.

Even if it manages to survive long enough that the very first participants get to withdraw more than they put in, that 'profit' they earn is actually money taken from those later users. Which is theft.
