Fiat is by "official decree", and is not voluntary.
The price discovery method for Bitcoin is the free market law of supply and demand.
A "dollar" is worth a "dollar" because "government" says it is.
Bitcoin is different. And whether you like it or not, five years from now, some people might be kicking themselves because they didn't look more into it.
Of course, Bitcoin is not gold or silver. But dammit, it's still better than unlimited fiat currencies run by joo banksters.
You can buy a couple hundred FRNs worth of bitcoins at an appropriate time, wait, and then sell bitcoins for thousands of FRNs worth of gold and silver bullion.
What other medium has gone from $0.001 each to ~$70.00 each? Hell even bitcoin at one dollar each is still a stupendous rise.
