Going back to the OP's situation then, you still haven't proven anything. The OP hasn't even stated his electricity costs. Not to mention, you're still running on the (possibly false) assumption that he is running four cards per rig, or has other means/methods of lowering the rig electricity draw per card to 25 watts. Like I already pointed out, not everyone run rigs full of four cards each. And for those of us that do not, our electric costs will be higher because of it. So, without purchasing a new motherboard and more mining hardware, he very well could have no choice but to mine at $7 of electricity per BTC.

If you reread you will find that he said it costs him .22 euros or .29 usd. I said that is crazy expensive and I don't blame him. Please stop assuming and just read...

And yet you're basing your "proven" $176 figure on $0.19/kwh...

lol, yeah everybody is on 15c electricity, what a happy world. Except u r full of BS. My own electricity is 19c, and I'm in US. The poster ALREADY SAID $7 is his equilibrium point, guess what? now the price is $6.5, that means he's mining unprofitably if he's still mining, which makes my analysis completely correct. So unfortunately you are the one spewing BS.

I said the average is 15c which is true. It costs me 8.5 cents so people do live below the average. You and I are in the minority hence why I said 15. For the average American it still makes sense to mine.

Just to prove you wrong some more. Ill use the same calculations as before except switch 15 to 19c a kwh.

it requires 91 cents per day to run a 5830 at 19c per kwh
160.68/91=$176.51

You make .1867 bitcoins a day with a 5830.

(.1867*6.5)-.91=30 cents per day if you sell today
