New Galactic Currency

I personally believe a new Galactic Currency is more important than some new world currency. Planet earth is limited while the galaxy is unlimited. In order for us to explore the galaxy, we have to be not limited by earth monetary system. There will have to be some exchange between earth monetary system and galactic currency. For example, 1 earth dollar = 10 000 galactic currency. This will enable people to travel on space ships. With this galactic currency, space stations etc. will come about faster.
