World currency unit

A world currency unit is a type of imaginary money used by people in different countries all around the world. It helps make buying and selling things easier and faster because it is the same kind of money everyone understands, no matter where they live. It also makes it easier to compare prices between countries. For example, if one country sells an item for 100 local currency units, it is the same as if another country sold the same item for 100 world currency units.
