🔐 Crypto Security 101: Stay Safe in the Blockchain World

Venturing into crypto? One of the most important things you can learn is how to protect your assets. Scams, hacks, and user errors are common—but avoidable.

🛡️ 1. Use a Secure Wallet

• Hot Wallets: Online wallets (e.g., MetaMask, Trust Wallet)

• ✅ Easy access

• ⚠️ More vulnerable to hacks

• Cold Wallets: Offline hardware wallets (e.g., Ledger, Trezor)

• ✅ Best for long-term storage

• 🔐 Immune to online attacks

🔑 2. Never Share Your Seed Phrase

Your 12- or 24-word recovery phrase is the key to your wallet.

• Store it offline (write it down, don’t screenshot it)

• NEVER share it with anyone—even if they claim to be from support

• If someone has your seed phrase, they own your crypto

🧠 3. Beware of Scams

Common red flags:

• 💬 DMs promising giveaways or investment returns

• 🌐 Fake websites with slight URL misspellings

• 📥 Phishing emails asking for wallet info

Always double-check links and use bookmarks for trusted sites.

🧱 4. Enable 2FA (Two-Factor Authentication)

Add an extra layer of protection:

• Use apps like Google Authenticator or Authy

• Avoid using SMS 2FA—it's vulnerable to SIM swapping

🔒 5. Keep Your Devices Secure

• Use strong, unique passwords

• Install antivirus & anti-malware software

• Keep your OS and apps updated

🚫 6. Don't Trade or Connect Wallets Blindly

• Only use verified platforms and DApps

• Review permissions before connecting your wallet

• Revoke access to unused DApps: https://revoke.cash

✅ Final Checklist

✅ Use cold wallets for big holdings

✅ Backup your seed phrase offline

✅ Enable 2FA

✅ Avoid clicking unknown links

✅ Stay updated on crypto threats
