Starting in crypto can be overwhelming. Before you buy your first coin, here are the three most essential terms every beginner needs to master:

1. Blockchain (The Tech)

It's the decentralized ledger technology that records transactions across many computers (nodes).

Why it matters: It makes data transparent, immutable (cannot be changed), and highly secure.

2. Decentralization (The Principle)

The core principle of crypto: No single person, company, or government controls the network.

Why it matters: It removes the need for trusted intermediaries (like banks), giving you sovereign control over your assets.

3. Private Key (Your Security)

This is the secret code (a long string of characters) that proves ownership of your crypto wallet.

Why it matters: CRITICAL! If you lose it, you lose your crypto. If someone else gets it, they get your crypto. Always keep it offline and safe.

🔥 Quick Tip: Never share your private key or seed phrase with anyone!
