Do you have any coins in your pocket? Take one out and look at it closely. It's round, right? Do you know why most coins are round? Here's why.↵
First of all, they're easy to use in daily life. You can pick up and hold round coins without worrying about sharp corners. Because there aren't any corners, the coins are safe and can't hurt people. In addition, they work well with machines. Round coins can roll, so they can be easily moved in vending machines and coin-sorting machines. This means that they won't get stuck in a machine. Furthermore, they are less likely to wear down. Coins are made to last for a long time. Corners often rub against things, so they wear down quicker. However, a round coin doesn't have this problem. Finally, round shapes are easily produced in factories. Circles are simpler than other shapes, so they're faster to make. Therefore factories can make many round coins at the same time.

These days, people often use their credit or debit card to buy things. But there are some great reasons to use cash too. First of all, cash is accepted by all sellers. Businesses need a special device for payments by credit or debit card. So, some smaller shops and restaurants only take cash. In addition, using cash can help you spend less. When paying with a card, it's common to spend more money. But with cash, you can see how much money you have. So it is harder to spend lots of money. Paying with money is great for both sellers and buyers!
