What is "money"? is the bigger question.
The fact that bankers can 'print' (on a computer) as much as they want, should give an idea of it's true "value". (like entering numbers in excel!!)
So what happens when we don't want or need it?
how much will FIAT be worth then?
Which raises the 2nd question "What can you do with 'money' " ?
Answer these 2 questions, get an "APP" to convert BTC (or similar) into old-school fiat as & when required, pay your barista & landlord in BTC and.... FIAT has zero value!
Once USA petro$ swaps to BTC-petro the USA debt will hurt! IMHO
