Blockchain.info has a stat for mining profitability based on electricity consumption of 650 watts per gigahash. This seems like a high figure to me in the age of ASICs. What would be a reasonable figure to use, based on ASIC machines currently in use? (as opposed to vapour-ware promised for next year).
I wrote to them complained about it a month ago. No reply. The figure is 6-8 mths out of date. The energy is down to a few percent of that. 650Watt is a GPU rig figure.
The 650 W is not the problem. What strikes me is that they know about the electricity costs of 200,000 miners. :-))))) Should be anything between 0 and 45$c.
