The national currencies of various states can depreciate, which is called inflation. Inflation in a particular country always, as a rule, arises due to the inept management of economic and even political processes in the state by the government or intentional narrow-minded actions of a number of state officials. If fiat is used correctly, it only has a beneficial effect on the economy of the state. Therefore, it cannot be said that fiat is already outdated, it should be changed to other financial systems.
