You're right, @ssd213 Fiat may be knocked about, but not knocked out. It is still 13 trillion plus collosus. Has BTC crossed USD 100 billion yet?
Beyond fiat, gold is also an option.
There is tremendous potential for bitcoin technology but let us not fool ourselves by thinking the world will move away from fiat.
The way the wheels are turning there may be no fiat, at all. The mainstream media is prepping us for the next collapse.
