Gold and Silver vs cryptos and fiat currencies

I will begin by saying Unapologetically that I believe God created gold and silver to be money. Man created fiat currencies. I do not believe that God’s plan for mankind is ultimately to have a corrupt monetary system controlled by a few central banks, who are in turn really just the front for a few Elite Oligarchs, who ultimately pull the strings behind the scenes. A debt based financial system is not scriptural, and in fact goes against scriptural principles. Therefore, why would God approve of it? https://aminutetomidnite.com/gold-silver/gold-and-silver-gods-true-money/
