Money is a tool that people use to buy goods and services. It can come in different forms, such as coins, paper bills, or even digital currency like Bitcoin. Money makes it easier to trade because instead of swapping items directly, you can use a common medium that everyone accepts. In addition to buying things, money also helps us save for the future. People often keep their money in banks to earn interest or to keep it safe. This way, they can plan for big expenses, like buying a house or going on a vacation, making money an essential part of everyday life.
