Hmm...how transactions in gold got processed without electricity?  Is this a serious question?    It's just too funny, though, they did seem to manage for thousands of years prior to the invention of the lightbulb.  To say that Bitcoin may "loose a bit of it's edge" without electricity, is the understatement of the year.  Let's be more accurate, Bitcoin is USELESS without electricity.  I'm not sure why this is even being called into question.
