Money
Some people fall for the cryptocurrency because they don't realize the beginning effects of their transaction. They are exchanging, for example, US Dollars (which are claimed to be near worthless) to a group of unknown priorholders in exchange for something which has no necessary demand.
THE VALUE OF THE US DOLLAR:
It is a fiat currency, which is backed by it's demand in use for taxes.
The US Dollar, issued and maintained in supply by the Federal Reserve,
Has Direction
To facilitate goals of the Federal Reserve, a branch of the Federal Government and governed by law, to:
Encourage full employment
Provide price stability
Realizing gains for the people through inflation
Redistributing ownership during deflation through competition for capital earnings (stocks and bonds)
Encourage innovation (productivity and efficiency) in Federal Government
Has Utility
For taxes
For products and services
For investment
The dollar only looses ratio value when inefficiently (as determined by the market) used or unused. This pulse is so we don't run out of products, services, or innovation (a deflationary force)
Government bonds are an investment in Government innovation
It encourages new earnings over old
The more the richer conserve, the more the Federal Reserve replaces their directive with higher value "new money"
Wages always grow faster than capital earnings
The basics "and up" get priority in innovation
Thus it is so much more than a fixed ratio of useless digitry.
-Broadly speaking, it is innovation to find the best way to use our talent and resources.
