What Is Bitcoin? Explained for Kids

Your kid has probably heard the word “Bitcoin” by now. Maybe from you, maybe from a YouTube video, maybe from a kid at school whose dad won't stop talking about it. Either way, they're going to ask you what it is. Here's how to answer without their eyes glazing over.

The short version (for when you're in the car)

Bitcoin is digital money. Nobody owns it or controls it. There will only ever be 21 million bitcoins, and people send them to each other over the internet without needing a bank. Think of it like email for money.

The longer version (for curious kids)

Regular money (dollars, euros, pesos) is created by governments. They can make more whenever they want. Bitcoin is different. A person (or group of people) using the name Satoshi Nakamoto created it in 2009, and they built rules into it that can't be changed. The biggest rule: there can never be more than 21 million bitcoins. That's it. Ever.

When you send a dollar to someone through a bank, the bank keeps track of who has what. With Bitcoin, thousands of computers around the world keep track instead. No single person is in charge. That's what people mean when they say Bitcoin is “decentralized.”

Parent talking points

• “Is Bitcoin real money?” Yes. People use it to buy things, save, and send money to each other. It's just not printed on paper.
• “Can I have some?” You don't need to buy a whole bitcoin. You can own a tiny piece, called a “satoshi.” There are 100 million satoshis in one bitcoin.
• “What if it breaks?” Bitcoin has been running since 2009 without stopping. Thousands of computers keep it going, so no single person can shut it down.

Try this at home

The 21 million game (5 minutes, ages 6+). Put exactly 21 dried beans (or coins, or LEGO bricks) on the table. Tell your kid: “This is all there is. We can't make more.” Now have them try to divide the beans between family members. What happens when someone wants more? They have to trade for it or earn it. That's how Bitcoin works. Nobody can just make more.

Materials: 21 small objects (beans, coins, LEGO bricks). Time: 5 minutes.
