The US Dollar money supply increased 500% in 5 years ($800b in 2008 to $3.6 Trillion in 2013) [Monetary base]. That is a lot of "money printing" (including digitally expanding the money supply).

There will come a time when the fact that Bitcoin won't EVER "print money" or expand the money supply is a HUGE value.

You say the currency supply "fluctuates". In the future, with 500% increases in US Dollar, the US Dollar can greatly drop in value. Over time, the fact that people know bitcoin can't expand the money supply is VERY VERY powerful.
