With the recent runup in Bitcoin price, I find that an S5 earns about $1/day NET of electric at the electric rate I am currently at.
No idea how long that will last, but on the other hand there are other areas of the US that have somewhat better rates for us SMALL miners than where I ended up at.
I too have to question this claim of $1/day in BTC
revenue, much less profit after electric. If you are basing your figures on bitcoinwisdom, as I have in the past, be aware that it's still using a BTC reward of 25BTC/block. Try a couple of other calculators and you'll likely find that the revenue
(i.e. before electric costs are subtracted), is more like 85 cents/day.
