In the past people are really dependent on those metals like gold and silver but since this is the age of computer. I don’t think that we will ever need those precious metals quotes unless we still want to leave on Dark Age. Back when nights and castles still exist.
The age of computer has proven that you could do trading with currency. All you have to do to go to your bank and you can withdraw the money that you earn from trading or from your job. I don’t think that those precious metals would still have the same appeal on people before. Although I do admit that people are still making a big deal of that but their time as the only way to barter things are now gone.
