Because cex.io is able to sell GH/s for more BTC than it will ever mine, they don’t have to have any mining capacity at all.

They can simply pay mining revenue out of the initial payment and keep the difference as profit.

The issue is that the market mentality of the people there drive the price well beyond anything remotely reasonable. I used to buy gh there while waiting for enough to accumulate to trigger an auto pay out. Often I sold them at a small gain in addition to the satoshis they mined. With the fees they have now that it isn't profitable to do even that.

with mining you are basically breaking even generally

your hope is that bitcoins will go up and you are holding the coins
