WTF WORLDWIDE - ANYTIME - ANYWHERE
The WTF can be used not only domestically but for international trade. You do not need actual WTF notes unless you wish to physically exchange them.
Example: A Chinese government firm wishes to sell 250,000,000 lucky charms in the shape of a four-leaf clover to Slovenia, in a deal worth 50,000 WTFs.
Slovenian state-owned private companies agree to send China 10,000 WTFs' worth each of Peking Duck, Sweet and Sour Pork, Egg Fried Rice, Spring Rolls and Hoi Sin Sauce.
In this case no WTFs need to physically exist. They are simply used to explain the value of the items, just like old-fashioned money.
Tip: Remember - money is pointless. What matters is all the stuff you can get.
