with difficulty currently at 112,000,000, 1GH/S at 1W/GH is less than a penny of electricity needed to produce 59 cents worth of profit per 24 hours.
lets crank that up now to 1,112,000,000 (that's a network hashrate of 10PH/S).. your electricity costs are still less than 5% of your profit if you're running 2W/GH.
As you can see, 1W/GH vs 2W/GH isn't going to matter at all until we see phenomenal network hash rates of hundreds of PH/S
icebreaker keeps claiming that 1W/GH vs 1.5W/GH is important, and this is just plain trolling as it does not make much financial sense at all.
I would also like to add that eASIC will be constantly fine tuning the watts/GH, so it's hard to believe that a leading ASIC designer is not going to have a competitive power efficiency in their chip design.
...still waiting for the punchline...
Holy crap man. Do you even
