Quoted from roffels:spending more resources than what you get"
i have a friend that mines bitcoins. he has 2 large tower looking things with huge heat sinks and 4 smaller tower things with 2 fans on each one. they run 24/7 his electirc bill alone more than tripled, and the heat these things put out is unreal. i dont have any figures as far as the electric bill but ill ask him.
