$PI 屁 is a poor people's currency, only absolute paupers are qualified to own it, KYC is short for屁民 verification.

There are still over a billion people worldwide without bank accounts, none of whom are rich; these groups are the target audience for屁.
Ideal use case: for example, buying cheap food so you don't starve to death on the same day (you can eat your fill for a few days before starving), that's all.
Hoping for屁 to increase in value is like searching for gold in a trash heap.
