1. What is Cryptocurrency and How Does It Work?

Cryptocurrency is digital money that operates on blockchain technology, a decentralized and secure ledger system. Unlike traditional currency, cryptocurrencies are not controlled by any government or bank.

Key Features of Cryptocurrencies:

✔️ Decentralized: No central authority like banks.
✔️ Digital & Secure: Transactions are encrypted on the blockchain.
✔️ Limited Supply: Most cryptocurrencies have a fixed supply, preventing inflation.
✔️ Borderless Transactions: You can send and receive money globally without intermediaries.

💡 Example: Bitcoin (BTC) is limited to 21 million coins, making it scarce like gold.

How Blockchain Works (Simplified):

A transaction is made (buying Bitcoin, sending Ethereum, etc.).
The transaction is verified by network participants (miners or validators).
It is added to the blockchain (an immutable ledger).
The transaction is confirmed and cannot be changed.

Now that you understand the basics, let’s explore how to start investing in crypto.
