The OP has no understanding of basic economics.

The value of any currency isn't "set" except by supply and demand.

100 years ago, you could buy a candy bar for $0.01.  Today that same candy bar is $1.00.  We didn't NEED to make the price more expensive, and it isn't more expensive at all, because the value of the US dollar has fallen 99x in 100 years.  So today's $1.00 is EQUAL to $0.01 from 100 years ago.

BTC will operate in the opposite fashion if it becomes widely used.  What costs 1BTC today might only cost 0.01BTC in 10 years, but the VALUE will be identical.
