Do you ever think that cloud mining will become profitable again?
It still is, just over a longer period of time.
This is not true. As it stands now it is not profitable having your GHs running at CEX. They will become even less profitable as time goes on as the difficulty tends to increase (although the adjustment in ~3 days will likely be an exception to this). You need to remember that when you are cloud mining verses "home" mining you are adding an additional layer of people who need to profit which will make it generally less profitable then if you purchased your hardware yourself
He never said CEX.IO. He said cloud mining. All the manufacturers offer their their own services now so it means being able to mine without having to pay for shipping, PSUs and ridiculously expensive electricity.
