try to determine how they are going to spin it before you agree
Good point. After that Bloomberg $150,000/day in electricity nonsense (which has been refuted, with the real number being more likely under $50K and dropping quickly thanks to ASIC), portraying bitcoin the way bubbleboy sees it is one likely aim:
in this scenario mining of bitcoins would suck a full 5 to 15% percent of the national electricity production, depending on the capital ratio.
I don't want to split hairs, but if the sheer order of magnitude of these numbers don't concern you, then you might suffer from the modern day version of the gold fever. There's just about no chance in hell a democratic society will allow such a behemoth to live (only to be subjected to the feudal whims of the early adopters that happened to be in the right forum 20 years ago, I might add).
