🔐 #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:
