wouldnt running 340 watts at the wall constantly 24/7 cost about $5 aday to run, which is what these are making at today difficulty so why bother?
WOW! cost less than $0.50 a day here
That's like $0.60 per Kwh! Can't be right.
I'm in the UK and we're on a "cheap" tariff £0.12/$0.20 per Kwh (£0.97/$1.63) and I make about £4.60/$7.70 per day in total at the current BTC value. But I do it because its an extension of my computing/electronics hobbies
My Kwh is 0.1050533 and that includes both generation and transmission. I just take the entire electric bill and divide it by the Kwh used. So it costs me about 86 center per day for each S3. With 10 S3s running I make enough in 1 week to pay for the entire month of electricity used.
