Can anyone actually show me how is it possible to reach ROI with cloud hashing of any kind. Please show me an example, BTC spend on leasing - expected mined BTC = profit. Is this possible and how? Factor in expected BTC difficulty increase pls.
This is what I get from CEX.IO

I earn about 0.1 bitcoin everyday. I reinvest back to GHS, so I gain about 10 GH everyday.
It is true that CEX.IO is about three time more expensive than your own hardware. But it's more convenient and flexible. I've been using CEX.IO for about three months now. According to my calculation, I will get ROI in July. It's safe to say that you will get ROI in 7-9 months.
It is true that the price of GH is dropping everyday. In Jan 17, 2014, GHS/BTC was 0.04571. Now it's 0.01044; four times cheaper. So if you are looking for day trading, you will lose money unless you are talented on trading. If you are focused on mining, instead (like me), you will eventually get ROI with assumption that CEX.IO will still be alive and kicking.
Many people complains about difficulty raising. But that's really wrong way of thinking. Difficulty is adjusted so that new bitcoins will be released in controlled manner (25 bitcoins every ten minutes). Forget about difficulty level, but pay more attention to total GH power of the network. Right now, total GH of the network is around 35,342,719.36 GH. How big is your GH compare to that? That's the question you should really ask.
It is true that total GH of the network grows rapidly. The real question is can you grow (and catch up) your GH at same pace (or faster preferably) as total GH grows.
