Money offers significant advantages over bartering as a medium of exchange. Unlike bartering, which requires a double coincidence of wants (both parties needing what the other possesses), money serves as a universally accepted means of payment, streamlining transactions. It also acts as a store of value, allowing individuals to save wealth over time. Furthermore, money functions as a unit of account, providing a standardized way to measure the relative value of goods and services, facilitating economic calculations and comparisons, ultimately promoting efficiency and economic development.
