🔐 #Crypto Security 101: How to Protect Your Crypto

1. 🏦 Use Reputable Wallets

Hot Wallets (Online): MetaMask, Trust Wallet, Phantom (more convenient, less secure).

Cold Wallets (Offline): Ledger, Trezor (highly secure, best for long-term storage).

💡 Tip: Store large amounts in cold wallets, use hot wallets for daily use.

2. 🛡️ Enable Two-Factor Authentication (2FA)

Always activate 2FA on exchanges and wallets.

Use apps like Google Authenticator or Authy — avoid SMS 2FA (less secure).

---

3. 🧠 Protect Your Seed Phrase

Your 12/24-word recovery phrase = your entire wallet.

NEVER:

Store it online or in cloud storage.

Share it with anyone.

✅ DO:

Write it down and store it offline in multiple secure places.

Consider using metal backups for fireproof safety.

4. 🚫 Avoid Scams

Watch out for:

Fake airdrops

“Support” DMs

Pump & dump groups

Phishing websites

✅ Check URLs carefully. Use bookmarks for exchanges and wallets.

❌ Never sign random smart contracts with your wallet.

---

5. 🧬 Verify Before You Sign

When connecting your wallet to a dApp (like Uniswap or OpenSea):

Read what you're authorizing.

Revoke access to old dApps at Revoke.cash.

---

6. 🔁 Keep Software Updated

Always update:

Your wallet apps

Your browser

Your hardware wallet firmware

Updates fix critical security bugs.

---

7. 💻 Use a Dedicated Device (Optional but Safer)

For high-value traders/investors:

Use a separate device just for crypto.

Use a VPN and antivirus software.

---

8. 🧾 Don’t Overshare

Don’t brag about your crypto holdings online.

Keep your wallet address private if possible.
