Can't wait till it goes down to REAL value of <$1 as many have free elec.
As many people have elec. paid for by others, others who will eventually find out and cut off abnormal use of that service.
Indeed. "Free" just means paid for by someone else. That someone may be awfully pissed when they find out who has been chewing the kilowatts.
There's another model of "free" too: solar power. I have just had 1.5kw of panels installed on my house. Of course, they only work during the day time, but even then I wouldn't mine with the generated power even when it's free. The power is worth more as an offset to my electricity bill than it is fed through the bitcoin sausage machine. Worse still, I get a feed in tariff bonus which means the power is worth even more not being used on bitcoin mining.
