If you are in the UK then at best your electricity cost will be 10 Pence /KWh more likely 15 pence? You will be loosing money on any of the Miners in the post above, and loosing even more as the Difficulty continues to rise. S7 would make a small amount of money for a couple of Months but then it will be loosing, also expensive.
So bottom line is it's a not starter at this point in time.
Rich
well he may have a strange power setup
So I will ask what does power cost you?
I am USA based and I get 9.7 usa cents per kwatt for the winter.
But I have a few free power deals and lost cost power deals
So I can run 20th using around 5200 watts but pay for only 3800 watts at the 9.7 cents.
And I am struggling to turn profit but I am turning profit.
