Stop using cloud mining if you really want to earn a profit just buy a miner cloud mining doesn't make any sense they are selling it to you for less just for you to make a profit when they could be running it instead of you? 
Such a discovery, wow 
Why not ask "why are they selling miners if they could earn more running them? Mining doesn't make sense!" LOL
You mean like KNC, Bitfury, and of course, BFL?
Anyway, you have to wonder why a cloud mining company would go through the effort and expense of buying miners, setting them up, running and maintaining them, and then go and sell the mined bitcoins at a discount to their customers.
The answer that comes to my mind is immediate gain. Cloud mining operations get the money upfront, just like it once was with pre-orders. Nowadays less and less people trust in pre-orders, so the sellers are offering cloud.
