The bitter truth about Fiat currency is that it will always depreciate in value.
What you can use $1 to buy in 10 years ago cannot buy it now.
and what you can buy now you can buy over 10 times ten years ago.
that is because we are the money is always depreciating and the reason why is depreciating is because it can be printed at any time is needed to its total supply is infinity.
but a true cryptocurrency and not a sheet coin or scam project will always appreciate because it has a finite total supply
