Throughout the course of history, humans have always moved to better forms of currency.
Beads -> Sea shells -> Wampum -> Metal Coins -> Gold -> Paper money fiat -> Electronic money (paypal, credit cards) -> Return to gold? Bitcoin?
This is me talking (C.H.)... and I have to point you to Gresham's Law:
http://en.wikipedia.org/wiki/Gresham's_law"When a government compulsorily overvalues one type of money and undervalues another, the undervalued money will leave the country or disappear from circulation into hoards, while the overvalued money will flood into circulation."
so, if Bitcoin's are "good money" there maybe a totally opposite effect to the "expected" ... humans are just so puny and inferior to their "own" Government's!
I truly hope Bitcoin's insurgence will be one time when Gresham is proven wrong!
