I pay 0,04 /kwh,

but you have to live in Russia for that

0,04??? wow
2,18 roubles, which is equivalent of 0,04 .
On the other hand, when I ordered 3x Antminer S1's a few months ago, they were delayed by the FSB (it's Federal Agency of National Security in Russia) because miners are cryptographic devices and probably they thought that I will hack the government with my miners

I had to go to the meeting with government officer and explain what bitcoin is, what miner is, and so forth.

Officer was amazed, by the way

But receiving that permission took 3 weeks, so my profit was cut very seriously.
On top of that, I have to pay 30% from any purchase bigger than $1000 (or several purchases in one month) to customs. And Russian Post is working like they are dead, three-four weeks delays in sorting facility is normal. So cheap electricity kind of the only plus ))
