When, I talk to people about bitcoin, they often tell me that it is BS because yoa can not use it without electricity. They are like, when electricity in your area will go off, you are poorest guy in world. I found that argument stupid, but dont really know what to tell them. for some reason they all count on not having electricity available...
Tell them this: credit cards, ATMs, and online bill payment won't work without electricity, either. Yes, you could still pay with cash, but who has thousands of dollars in cash laying around at home? You should always have some for emergencies, but if electricity is out for weeks or more, there will be major major problems.
