Could The Whole World Use Just One Currency?

Imagine if everyone on Earth used just one coin to buy everything, that’s what having just one currency would be like.

Right now, countries use different currencies, like dollars, euros, or yen. It's like if you and your friend each had a different kind of candy, you trade yours for theirs when you want something new. But if all the kids in the whole world used the same candy, trading would be much easier!

If the whole world used just one currency, people wouldn’t need to exchange money when they travel or do business with others. It would be like having a single kind of toy that every kid in the world plays with, no more switching from blocks to cars.
