Bitcoin is a kind of digital money. You can't hold it like a coin or a paper bill, but computers can keep track of it.
How can it move? You can send bitcoin to someone else over the internet using a wallet. Each wallet has an address, a bit like a special mailbox for bitcoin.
The shared record. Bitcoin uses something called a blockchain. Think of it like a giant shared notebook. Many computers (sometimes called miners) check the notebook and update it together, so everyone is using the same record.
Think of it like a class scoreboard. When someone earns points, the teacher writes it down and everyone can see it. The scoreboard is fair, hard to change, and everyone can check it.
Good to know. Prices can go up and down, not every store accepts bitcoin, and there are scams, so always ask a grown-up and stay safe online.
Remember: bitcoin is digital money, it lives on the internet, many computers share one record, and it is different from cash in your pocket. Smart, safe, and curious is the best way to explore!
What to remember

For grown-ups
Bitcoin is a decentralized digital currency recorded on a public ledger called a blockchain, maintained by many computers rather than a single bank. Transactions move between wallet addresses and are verified by a network process (mining). It is volatile, not universally accepted, and a frequent target for scams, so it is best framed for kids as “digital money many computers track together,” with a strong note that grown-ups should handle real accounts.
