Cex.io is a market based commodity. If the new hashing power brought on by cex was actually driving the price down, we would see much lower prices already. But cex brings new power on priced at the average price at the time so as not to upset the market. GHS is not IMO something that should be price regulated by a market. I would like to see a company selling GHS at an ever decreasing rate as their cost per GHS drops. With perhaps a small side market for p2p sales for times when the company has run out of GHS for the moment, but with the majority of GHS being purchased from the company hosting said GHS.

You are mistaken to make any assumptions or decisions based on what cex is trading GHS for. The people/bots trading GHS on cex are out to make a profit buying low and selling high. This is in stark contradiction to supply/demand and moores law. They are not buying and holding looking to make profit via mining, if the majority were then the price would be pushed down with each subsequent jump in difficulty.

I had a ton of GHS with CEX, but when I read about petamine I cashed out 95% of them and bought shares. Pyramining, petamine, cognitive, etc are the places to be invested in, rather than buying from overpriced cloud mining "services" or even trying to run your own hardware at quantities needed to make a profit.
