Answer:
There are many theories about the origin of money, in part because money has many functions: It facilitates exchange as a measure of value; it brings diverse societies together by enabling gift-giving and reciprocity; it perpetuates social hierarchies; and finally, it is a medium of state power. It’s hard to accurately date interactions involving currency of various kinds, but evidence suggests they emerged from gift exchanges and debt repayments. Money also allows others to trade goods and services indirectly, communicate the price of goods, and it provides individuals with a way to store their wealth over the long-term.
