Everyone believes value of money
Money is just a sheet of paper, but why do we think it has value?
Money is just sheets of paper.
If nobody believes that 100USD is money, you can use it to blow your nose, or to take a note, or fold origami, or feed it to a goat because it has no value.
How about you draw your face on a sheet of paper and say it is a 100USD note. You cannot use it at a shop, right?
Why can paper money be used as money?
