Zim: "On average, mining one bitcoin consumes approximately 650 kWh, which equals the typical monthly electricity consumption of an American household."
I don't understand. The typical American family probably pays $500 for a month's electricity. But the article says, or at least implies, this would be enough for one bitcoin...which can be sold for $100,000?
Yeah, I'd say that is "worth it". But I would also say that can't possibly be even remotely true? Maybe the mean TEN YEARS of electricity for one bitcoin? That would be $500/m x 12 m/yr x 10 yr = $60,000. So even that can't be enough? Maybe 20 years for electricity average use to get one coin?
