I found it quite reasonable to ask why any Gran, Joe or Janet in the first world would bother using an alt currency when they can use CC or PayPal or OK Pay etc.
I fully agree, virtually impossible to push trough the idea to the general public. There is another, perhaps bigger issue with the Vericoin VISA card, a conceptual problem. Eventually crypto currencies will be accepted and used, but certainly not via conventional payment schemes such as VISA. Quite the opposite, crypto currencies will succeed because this new money address the shortcomings of conventional payment schemes.
