🔐 CryptoSecurity101: The Essentials

1. Use a Secure Wallet

• Hot Wallets (e.g., MetaMask, Trust Wallet): Convenient but connected to the internet—use for small amounts.

• Cold Wallets (e.g., Ledger, Trezor): Hardware devices not connected to the internet—ideal for long-term storage.

✅ Tip: Always buy hardware wallets from official sources to avoid tampered devices.

2. Protect Your Private Keys & Seed Phrase

• Never share your seed phrase or private keys.

• Write them down offline and store in a fireproof, waterproof location.

• Never store them in cloud storage, email, or screenshots.

3. Enable Two-Factor Authentication (2FA)

• Use apps like Google Authenticator or Authy for exchanges and wallets.

• Avoid SMS-based 2FA due to SIM-swap risks.

4. Beware of Scams & Phishing

• Double-check URLs and only use official links.

• Be cautious of fake airdrops, giveaway scams, or DMs offering “support.”

• Bookmark your frequently used sites (like exchanges or DeFi platforms).

5. Use Reputable Exchanges

• Stick to well-known, regulated exchanges.

• Enable withdrawal whitelists and withdrawal delay features if available.

6. Keep Your Software Up to Date

• Update wallets, browsers, and antivirus software regularly.

• Consider using a dedicated device for crypto transactions.

7. DYOR — Do Your Own Research

• Don’t rely on hype or influencers.

• Research new projects thoroughly before investing or connecting your wallet.

8. Test Before Trust

• For new DApps or smart contracts, try with small amounts first.

• Revoke token approvals you no longer use (Revoke.cash is a great tool).
