Well, considering I have been a banker my whole life and I absolutely have no idea what a bitcoin is, except something that is digitally created and it supposedly has some worth, I guess I am not sure of any need to create an unknown and totally unregulated form of exchange. Maybe I am just old, but what is wrong with old fashion currency and credit cards unless you believe the conspiracy theorists regarding the fallacy of the current economic systems. They say they can't be counterfeited. I find that just a little beyond believe as everything is scammed sooner or later.
Personally, if the world comes to an end, I think I will stay with my gold coins over digital money when the electricity goes out.
