Interesting that the mere mention of "fiat currency" invokes tin-foil hat. Whether Bitcoins can survive the volatility is indeterminate. If it does survive, however, and becomes an alternative to (avert your eyes) fiat currencies, the impact will be far greater than another obscure fiat currency suddenly being used.

A fiat currency can't become an alternative to fiat currencies; it can only become a better managed fiat currency by way of being an algorithm rather than a human. Bitcoin is an obscure fiat currency suddenly being used.
