#CryptoSecurity101 #CryptoSecurity101 – A Beginner's Guide to Staying Safe in Crypto
Whether you're trading, investing, or just exploring the world of cryptocurrencies, security is crucial. Here's a quick and essential primer:
---
🔐 1. Use a Secure Wallet
Hot Wallets (online, e.g., MetaMask, Trust Wallet): Convenient but vulnerable to hacks.
Cold Wallets (offline, e.g., Ledger, Trezor): Best for long-term storage.
Tip: Store most of your crypto in cold wallets; only keep what you need for daily use in hot wallets.
---
🛡️ 2. Enable 2FA (Two-Factor Authentication)
Always use apps like Google Authenticator or Authy—avoid SMS-based 2FA if possible.
Never share your 2FA codes or backup phrases.
---
🧠 3. Never Share Your Seed Phrase
This 12–24 word phrase is your master key. Anyone who has it controls your wallet.
Write it down, store it securely offline, and never enter it on unknown websites.
---
🕵️ 4. Avoid Phishing Scams
Check URLs: Fake sites often mimic real ones. Bookmark trusted platforms.
Don’t click on links from unknown DMs or emails.
Use browser extensions like MetaMask’s phishing detector.
---
💻 5. Secure Your Devices
Keep your OS and apps updated.
Use antivirus software and avoid downloading sketchy files or apps.
Avoid public Wi-Fi when accessing wallets or exchanges.
---
⚠️ 6. Be Careful with DApps and Smart Contracts
Don’t sign random transactions or connect your wallet to unknown platforms.
Use platforms like Etherscan or BSCScan to verify contracts.
---
📚 7. Keep Learning
Follow trusted sources like CoinDesk, Binance Academy, or Decrypt.
Be skeptical. If it sounds too good to be true, it probably is.
---
🧾 8. Backup Everything
Keep multiple secure backups of your seed phrase and important files (not online).
Store backups in fireproof safes or secure, separate locations.
