I've been learning a litle bit of Economics by myself. I was reading about how the money is established by a country. I'm working on understanding about fiat money, but I've been reading about people discusing about the importance of adopting a metallic currency, like gold or silver. This people say Central Banks are not necesary for having a healthy money. https://www.youtube.com/watch?v=NwHdSl1ASbA https://www.youtube.com/watch?v=cJ9mMEDoN5s How good is the idea? Do we have a good opportunity in adopting a metallic standard instead of fiat money?
