How Do ‘Cryptocurrencies’ Work and Why Are They Valuable?

Cryptocurrencies are like magic coins on the internet. You can send them to friends, buy things with them, and no one else needs to be involved. They’re valuable because people believe in them, just like how gold is valuable because everyone thinks it’s special.

They use something called blockchain, which is like a secret notebook that everyone can see. Every time you send money, the notebook updates so everyone knows who has what.
