De
currency is simply the vehicle to purchase other things and has a standard value. You can take it and go buy Gold, silver, diamonds, platinum, whatever and then hold onto what you bought..
You will likely discover that merchants or people won;t take yer gold bullion for payment and give you change back.. Its why the fiat money was once backed by Gold reserves and some nit wit decided to use the credit system as the backing..
No doubt Gold reserves are the best think behind currency but its kinda difficult to go pay for a candy bar with a bar of gold..
