What Are Satoshis? Explained for Kids

When your kid hears that one bitcoin costs tens of thousands of dollars, the first thing they'll say is “well, I can't afford that.” Good news: they don't need a whole one. Bitcoin splits into tiny pieces called satoshis, and this is where it gets fun for kids.

A satoshi (or “sat”) is the smallest unit of bitcoin. One bitcoin equals 100 million satoshis.¹ Named after Bitcoin's pseudonymous creator Satoshi Nakamoto, satoshis let anyone own bitcoin for just a few cents. If bitcoin is $80,000, one dollar buys you about 1,250 sats.

What is a satoshi?

A satoshi is the smallest unit of bitcoin. There are 100 million satoshis in one bitcoin.¹ If bitcoin is a dollar, a satoshi is like a fraction of a penny, except way smaller.

The name comes from Satoshi Nakamoto, the person (or group) who created Bitcoin in 2009.¹ Nobody knows who they actually are. Kind of wild that the world's most influential financial invention was built by someone who disappeared.

How do you explain satoshis to a little kid?

“You know how a dollar breaks into 100 pennies? A bitcoin breaks into 100 million pieces. Each piece is called a satoshi. So when someone says they have 10,000 satoshis, that's a real amount of bitcoin. It's just a small piece.”

Another way: “Imagine a pizza. A whole pizza is one bitcoin. A satoshi is one tiny crumb. But if the pizza is worth $80,000, even a crumb has value.”

Why do satoshis matter?

Most people will never own a full bitcoin. That's fine. You don't need a full ounce of gold to own gold, and you don't need a full bitcoin to own bitcoin. With only 21 million bitcoin that will ever exist, the total number of satoshis is 2.1 quadrillion.¹ Plenty of units for 8 billion people.

Thinking in satoshis instead of whole bitcoin makes it less intimidating. “I own 50,000 satoshis” sounds better than “I own 0.0005 bitcoin.” Kids (and adults) respond better to whole numbers.

What does “stacking sats” mean?

“Stacking sats” means buying small amounts of bitcoin regularly. $5 here, $10 there. It's the Bitcoin version of putting coins in a piggy bank. A lot of Bitcoin parents set up automatic buys of $10-$25 per week for their kids through platforms like River. Over years, those sats add up.²

Dollar-cost averaging (buying a fixed dollar amount on a regular schedule) means you buy more sats when the price is low and fewer when it's high.³ It takes the stress out of timing the market. If you're thinking about setting this up, our guide to how to buy bitcoin for your child walks through the whole process.

Kid questions about satoshis

• “How many satoshis can I get for $1?” Pull up the current price together and do the math. If bitcoin is $80,000, then $1 buys you about 1,250 sats. If it's $100,000, you get 1,000 sats. Kids love doing this calculation.⁴
• “Will my satoshis be worth more later?” Maybe. If more people want bitcoin and the supply stays fixed at 21 million,¹ each satoshi could be worth more. But the price goes down sometimes too. For the full picture on saving, check out Bitcoin savings accounts for kids.
• “Can I spend satoshis?” Yes. Some apps let you buy gift cards or pay for things with satoshis using the Lightning Network.⁵ It works just like spending any other bitcoin, just smaller amounts.
