Re: what's the most efficient mining hardware available? (bachelor thesis)
Interestingly it is really considerable to buy some GH on cex.io, because if the prices keep on not going down you can sell them after a period and had the mining for free.
lol.
Anyway, it is always fun to see guys spamming their cex.io referral links, and then lure newbies to the site.
You can find lots of them here.

I didn't want to get started on cex.io, which in my opinion is the single largest treat to bitcoin that exist, Santoshi warned about companies like them.
