I do not think of it as a negative thing...
here:
It will be more like this:
Difficulty increase -> miners need more GHs -> more demand in GHs -> prices go up in CEX
Not this:
Difficulty increase -> miners panic-selling -> selling GHs CHEAP -> prices go down in CEX
Let's be realistic. Obviously, the increased difficulty and the introduction of maintenance fees means the overall value per GH has been dramatically reduced. If you will pay twice as much for half the return, I have a bridge to sell you. In reality, the value of the GH should naturally diminish over time however, it also pays a dividend. With that you can make and informed decision. I see 0.1194/GH/s at the second. I don't think I'm buying into that today. If it got near 0.08 I'm sure you would have a large volume of buying. I believe the bots have some control over cex.io at the moment and artificially inflate the numbers. At that point, you are just day trading. That's a whole different game but destabilizes the exchange.
IMHO
Well said, I agree with your analysis and I duly expect the 8th to be a day which GHS/BTC prices will fall.
