I just don't get why everybody is crying about how economically disadvantegous it is to buy GHs at CEX.io and at the same time are people buying hardware at much higher price per GHs like Antminer U1 here
https://bitcointalk.org/index.php?topic=386170.0 . Am I missing something?
Of course GHs price will go down with rising difficulty, but this has nothing with cex.
Price depreciation of hardware no matter who you buy or rent from.
If you buy hardware then you can't use it for anything else after mining.
If you rent the hardware then if depreciates in price on the exchange faster than any Nitcoin you can mine.
Both are losers.
Try Satoshi dice instead.
