🧠 What is Cryptocurrency?
Cryptocurrency is a form of digital money that exists only online. It’s decentralized, which means no single person, bank, or government controls it. Instead, it’s managed by a network of computers (called nodes) using cryptography (hence the name).
Unlike traditional currencies (like USD, EUR, or GBP), cryptocurrencies are:
- Borderless – can be sent worldwide instantly.
- Decentralized – no central authority controls them.
- Limited in supply – many have a max cap (e.g., Bitcoin: 21 million coins).
- Public & Transparent – transactions are recorded on a blockchain, which anyone can view.
🔗 What is a Blockchain?
Think of a blockchain as a digital ledger or spreadsheet that’s duplicated across thousands of computers. It records every single transaction made with a specific cryptocurrency in a secure, tamper-resistant way.
Each block contains:
- A batch of recent transactions.
- A timestamp.
- A reference to the previous block (creating a chain).
This tech is the backbone of most cryptocurrencies.
💰 Popular Cryptocurrencies
