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.
Exactly, what is the difference...they won't make money with AntMiner either and it will be harder to sell too. Fact is, you need lots of money to buy the very best if you are in this for profit.
