You know what's weird to think about? Money- it doesn't have ANY value whatsoever. If you think about it, there is no logical reason that anyone would want a piece of paper or a coin in exchange for a good or service that us humans either want or need. And, anything in theory could become a currency, my proof is that the currency in the US is LITERALLY a piece of paper. Just a crazy thought that crossed my mind, so I figured I would share it.
