Paper money is a bit like virtual money, as its virtually worthless, except for the trust that you can trade it in at your central bank for gold.
I surely hope nobody actually trusts that, as by no means can everyone's dollars ever be traded for gold.
Oh, and what makes gold worth anything in the first place? Right: the same kind of properties that Bitcoin also has by nature (and fiat money doesn't).
That's my point, after Cyprus and other banking fiasco's, people are loosing their trust (rightly so) in fiat currency, and bitcoin is gaining trust, and accepted by more and more vendors more and more frequently.
Long live the bitcoin
