🔐 #CryptoSecurity101 — Fundamentals of Crypto Security

1. 🛑 Never share your private keys

• Private key = your master password. Whoever has it controls your cryptocurrencies.

• Seed phrase: a list of 12 or 24 words generated by your wallet. Store it offline, on paper or a secure device, never in the cloud or in screenshots.

⸻

2. 💼 Choose the right wallet

• Hot wallet (connected to the internet): useful for daily use, but more vulnerable to attacks.

• Eg: MetaMask, Trust Wallet

• Cold wallet (offline): ideal for long-term storage.

• Eg: Ledger, Trezor

⸻

3. 🔐 Enable two-factor authentication (2FA)

• Protect accounts on exchanges like Binance, Coinbase, or Kraken.

• Use apps like Google Authenticator or Authy, not SMS (they are easier to intercept).

⸻

4. ⚠️ Beware of scams

• Never send crypto to strangers promising to return more.

• Always verify the URL of the website.

• Be wary of direct messages on social media about “safe investments.”

⸻

5. 🧠 Do DYOR: Do Your Own Research

• Do not blindly follow advice from influencers.

• Research the project, its team, purpose, and code (if you know how to read it).

• Use reliable sites like CoinMarketCap, CoinGecko, or Messari.

⸻

6. 📉 Be careful with smart contracts

• Do not sign transactions without knowing what they do.

• Connect your wallet only to audited or known sites.

• You can use tools like DeBank or Etherscan to see what permissions a dApp has over your wallet.

7. 🔍 Monitor and revoke permissions

• Use Revoke.cash or Etherscan Token Approvals to see and remove unwanted access to your tokens.
