Yeah, I've been writing about it on my riddle thread for some time.  We should see the war on cash escalate very quickly later this year.  By next year most major countries will ban cash.

And I wonder what they'll use instead?  Bitcoin should go into hyper mode and explode later this year and a few other competing currencies backed by opposing forces will follow suit and I think a global battle will ensue for which coin will be the one global currency.
