Alot of people are saying that money is just a medium of exchange. I disagree with this definition. Alot of people are willing to exchange something for money(sell), but they often refuse to exchange their money for something (buy) other than the basic commodities. This makes it mucxh harder to trade something for other people's money. So even as a medium of exchange, there is an inbalacne of trade.
alot of people WOULD exchange their money for food, energy water heat and electricity But other than this, it is very difficult for people to cough their money.
