What Is Cryptocurrency?

How Does Cryptocurrency Work?
Cryptocurrency transactions work through a combination of blockchain technology and digital wallets.

- Once verified, it is permanently recorded on the blockchain.
This process makes transactions transparent, secure, and resistant to manipulation.
