Crypto uses tools like blockchain and smart contracts. These tools make sending and receiving money easy, fast, and safe. Crypto is open to everyone. You do not need a bank account to use it. This guide will help you learn more, even if you are new.

How Does Cryptocurrency Work?

Here’s how the system behind cryptocurrency works in simple terms:

1. Blockchain
   
   • A blockchain is a digital record.
     
   • It keeps track of all crypto trades.
     
   • Many computers check and save this data.
     
   • This keeps it safe and fair.
     
2. Decentralization
   
   • Crypto is not run by one company or bank.
     
   • Many people and computers help keep it running.
     
   • This means no single person has control.
     
3. Mining
   
   • Some coins like Bitcoin need mining.
     
   • People solve hard problems with computers to add new data.
     
   • They get coins as a reward.
     
4. Wallets and Keys
   
   • You keep your crypto in a digital wallet.
     
   • You use a private key, like a password, to send money.
     
   • You must keep your key safe.
