What is a Cryptocurrency?

A cryptocurrency is digital money that runs on blockchain technology

Unlike traditional money:

• No bank controls it

• No government directly issues it

• Transactions happen peer-to-peer

Simple Example

When you send money using a bank:

• Bank approves the transaction

• Bank records it

  
  

With crypto:

• The blockchain records it

• No middleman needed
