## **1. What Are Crypto Coins?**

Cryptocurrencies (or **crypto coins**) are **digital or virtual currencies** that use **cryptography** for security and operate on **decentralized networks** (usually blockchain). Unlike traditional fiat currencies (USD, EUR, etc.), they are not controlled by governments or central banks.

### **Key Features:**

- **Decentralization** – No central authority (like a bank) controls them.

- **Blockchain Technology** – Transactions are recorded on a public ledger.

- **Limited Supply** – Many cryptos (like Bitcoin) have a fixed max supply.

- **Pseudonymity** – Transactions are linked to wallet addresses, not identities.
