No matter what though, there will be a "Madoff" somewhere. But yeah, we are on the same page as far as relying on electronic currency. Whether it's the Madoffs, hackers, viruses, technical glitches, corruption, or even possible natural occurances that effect electronics, to me there are too many "What if" scenarios you can play out by relying on electronic currency.
But as far as a global currency, personally, I think something like that is long overdue.
