Cex.io the company behind Ghash.io offers cloud mining.
Do not buy this. You will end up mining in the Ghash pool which is nearing 51% hash rate of the total network.
Which, in simple language, gives certain people the ability to perform a mass fraud (double spending) in bitcoin.

1/ It is not for sale it is free
2/ It has nothing to do with mining its for trading
That being said, I cant get it to work, it wont trade and it wont re-invest for me, so not a very good start is it.
