Around 2700 years ago , the first coins in electrum (alloy of gold and silver ) are probably only an "award" to develop the social links and the fair work.
Later, Gold and Silver are excellent reserves of value , but bad mediums of exchange …., with a negative environmental and social impact to find new mines to increase gold and silver supply. .
The fiat money and the “money like”, created by private banks credits , are good mediums of exchange , but also bad reserves of value because of inflation.
The tokens
have no value, but are the best mediums of exchange … at the local level.
And
tomorrow ..... ????
