The US dollar or USD is the currency of the United States and its overseas territories (such as Puerto Rico); it is also that of Ecuador, Zimbabwe, the Federated States of Micronesia, Marshall Islands, Palau, Panama, El Salvador, East Timor, Turkey Islands and Caicos, the British Virgin Islands and BES Islands. It is divided into 100 cents.
Its ISO 4217 code is "USD", with the name "dollar of the United States." Its symbol is "US $" or just "$" (Unicode character U + 0024). But that symbol is used locally to refer to other national currencies (eg the peso in Mexico).
The US dollar is the currency most used in the world for transactions, and since December 2006, the second to the euro in terms of money in circulation.

This is no longer the case. Furthermore, the argument that every bitcoin is covered by the amount of electricity used during extraction is quite possible.
In total contrast to traditional currencies, Bitcoin:
