Cryptocurrency is a type of digital money that exists only online. Unlike regular money (like dollars or euros), it’s not controlled by any bank or government. Instead, it runs on a special technology called blockchain, which keeps everything secure and transparent.
The most well-known cryptocurrency is Bitcoin, but there are thousands of others like Ethereum, Litecoin, and Solana.
How Does Cryptocurrency Work?
Here’s how it works in simple terms:
- You store your crypto in a digital wallet (like an app or device).
- You can send or receive crypto instantly, anywhere in the world.
- All transactions are recorded on a blockchain, a secure and public online ledger.
- Once a transaction is added to the blockchain, it can’t be changed or erased.
No banks are involved, and you have full control over your money.

People like crypto because it offers:
