We all need cash in order to live our lives. However, something called digital currency is slowly taking the place of cash. Digital currency is a kind of money. Usually, we use currency when we talk about a country’s money. If something is digital, it only exists on a computer. So “digital currency” means money that only exists on computers.
Lots of people have digital currency accounts. They use a credit card to change their real money into digital money, and then the money goes into the digital currency account. A lot of people wonder, “Why in the world should I change my real money into digital currency?” This is a fair question, but there’s a good answer. If you want to buy something online,
then you usually have to use digital currency. For example, if you’re in China and you want to buy something in Canada, then you’ll have to pay with digital currency.
Many people still don’t trust digital currency. Some people think that if they can’t hold their money in their hand, then it doesn’t seem real. These people don’t feel comfortable when they see numbers on a computer screen. The computer tells them that their money is safe but these people don’t really feel safe. Another problem is security (安全). There are hackers all over the world. A hacker is a person who steals computer information. If a hacker gets the password of your digital currency account, he or she can steal your money.
You have to decide whether or not you trust this new invention. Just remember one thing: If you want to buy something online, then you probably won’t have a choice. You’ll have to use digital currency.

A. What digital currency is.
