For those long time purchasers of precious metals, understanding what is fundamentally money and the difference between it and currency, is easy.
Precious metals have been money throughout history.
Their luster is desirable to all peoples throughout the world regardless of culture, education, or any other demographic that one can find.
Precious metals are of course “precious” meaning that they are limited in their availability and the enormous time and resources required in order for one to be able to attain these metals.
Bitcoin too is money because it contains all the aspects of money that precious metals do.
