🔐 #CryptoSecurity101: How to Stay Safe in Crypto
Crypto is powerful, but it also comes with risks. Understanding how to protect yourself is non-negotiable.
🔹 1. Private Keys & Seed Phrases
Your private key or seed phrase (usually 12–24 words) gives full access to your wallet.
NEVER share it. NEVER store it online.
Losing it = losing your funds.
Sharing it = someone will drain your wallet.
✅ Use:
Offline backups (e.g. paper, metal wallets)
Multiple secure locations (but not cloud storage)
🔹 2. Hot Wallets vs. Cold Wallets

Recommendation: Use cold wallets like Ledger or Trezor for large amounts.
🔹 3. Beware of Phishing Attacks
Fake websites, pop-ups, or messages pretending to be from exchanges or wallets.
Always check URLs, bookmark official sites, and never click on random links from social media or email.
🔹 4. 2FA (Two-Factor Authentication)
Always enable 2FA using apps like Authy or Google Authenticator (never SMS if you can help it).
Avoid using the same passwords across platforms.
🔹 5. Smart Contract Risks (DeFi)
Not all DeFi platforms are safe.
Risks: bugs, rug pulls, flash loan attacks.
✅ Do your own research (DYOR):
Look for audits, team transparency, TVL, and community reviews.
🔹 6. Exchange Risks
Even big exchanges can get hacked or go bankrupt (see: FTX).
Don't store all your funds on an exchange.
🔁 Golden Rule:
“Not your keys, not your crypto.”
🔹 7. Scams to Avoid
✅ Fake giveaways ("Send 1 ETH, get 2 ETH back")
✅ Pump-and-dump groups
✅ Impersonator accounts
✅ Unverified token airdrops (might drain your wallet)
🔹 8. NFT & Token Approval Risks
Granting token/NFT approvals can give malicious contracts access to your assets.
🧹 Use tools like:
