Re: Cex.io: the largest Bitcoin cloud mining service, not a profitable investment

The way I see it, if a cloud mining service can make more money mining then what they're charging, then they'd just mine. Having me pay them to mine for me seems like I'm losing out.

If they can sell their GH for BTC and buy more GH for those BTC they might make more money than if they just mine them self.

Please provide an example of how that might work. I think you will discover that it only works if the customer loses money.

If it cost them .01 BTC to make/buy 10 GH/s worth of mining equipment but can sell that equipment on cex.io for .07 BTC then they just made .06 BTC, they then use that .07 BTC to build/buy 70 GH/s and sell that for .49 BTC, and so on and so forth. The only difference is that the amounts are much greater (I am not sure about the profit margins though).
