How is using currency easier than using bartering?

Using currency simplifies transactions by providing a common medium of exchange, eliminating the need for a double coincidence of wants required in bartering. It allows for standardized pricing, making it easier to compare the value of goods and services. Additionally, currency can be stored and saved for future use, facilitating long-term planning and investment, while bartering often requires immediate exchanges. Overall, currency enhances efficiency and convenience in trade.
