Cryptocurrency is a type of digital money that works on the internet. Unlike paper money or coins, it does not exist in physical form. Instead, it is stored in digital wallets and runs on special technology called blockchain. Many people around the world use cryptocurrency for trading, payments, and as an investment.

What is Cryptocurrency?

Cryptocurrency is a virtual currency that uses cryptography for security. This makes it very hard to hack or copy. It is decentralized, meaning no bank or government fully controls it. Transactions happen directly between users through secure online systems.

How Does Work?

Cryptocurrency works through blockchain technology. A blockchain is like a digital record book that stores all transactions in blocks. These blocks are linked together in a chain, making it nearly impossible to change past records.

When you send cryptocurrency to someone:

1. The transaction is verified by computers (called miners or validators).
2. The verified transaction is added to the blockchain.
3. The receiver gets the digital coins in their wallet.
