Currency
There are many ideas for future currencies, when it comes to trade, the following currencies are usually used [in order of use]:
-Great british pound
-US dollar
-European Euro
However, we do have our own de facto currency too, called Smelly oats
the Smelly oat symbol is ζ ζ ζ [in different fonts for comparison]
1 smelly oat is rougly 20 pence [0.2 GBP] or 5 Smelly oats = 1 GBP
