Money is a fiction and it tends to feel like money is a factor of nature and evolution of money is the factors that we made that changes over time . In 550 BC the Greek came up with coins as a main form of exchange until 1000 AD when china invented paper money as a major economic revolution . The new York stock exchange made Trillions of dollars during the covid-19 times and when trading in stocks you can either gain huge amount of money or loose the same huge amount of money. After China Invented the paper money in 1000 AD they later went back to metal money, Do you think that metal money was more reasonable than paper money which is more of a fictional thing ?
