Bail the F' out of BFL and buy other HW. They're charging 2$ per GH and you can get other stuff as low as $0.70 per GH.
Depends. I could sell you a Single/50 for $25 bucks. That would be .50 per gh, is it a good deal?
How about ten bucks? .20 per gh. Super deal, right?
Answer: No because the unit pulls 200 watts to make 50gh. The number is power and price and gh performace.
