Security Guide – How to protect your digital assets

As crypto adoption grows, cybercriminals become more active — using phishing, malware, and impersonation to steal your assets.

To secure your crypto, you must consider multiple attack vectors and implement strong practices across three layers of security:

🔐 Three layers of security

🧱 1. Network Layer

• Are your private keys cryptographically secure?

• Is the blockchain safe from attacks (e.g. 51%)?

---

🧩 2. Application Layer

• Do you use trusted apps or exchanges?

• How are your funds stored?

• Is your account login secured with strong passwords and 2FA?

---

🌐 3. Real-World Layer

• Are your devices encrypted and secure?

• Is your 2FA setup safe?

• Have you set up inheritance or recovery instructions in case of death?

Your #1 job as a crypto holder: Protect your funds. Self-custody and cold storage are key.

🚨 Common Mistakes That Lead to Loss

• Reusing weak passwords

• Skipping 2FA

• Sharing or exposing private keys

• Saving keys or passwords online

📧 Email Security for Crypto

🔑 Why Email Is Important

Your email is the gateway to all your crypto accounts. It must be locked down.

✅ Best Practices:

• Use trusted providers: Gmail, Outlook, Protonmail

• Always enable 2FA on your email

• Create a separate crypto-only email

• Be wary of phishing emails that try to scare or trick you

⚡ Quick Tips:

• Never trust email links

• Double-check the domain of login pages

• Use anti-phishing banners if your exchange offers one

• Visit haveibeenpwned.com to check for data breaches

🔐 Two-Factor Authentication (2FA)

📲 What You Need to Know:

• Enable 2FA everywhere (email, exchange, wallet, social media)

• Use authentication apps, NOT SMS (SMS is vulnerable to SIM swaps)

🛡️ Backup Codes:

• Store them offline and securely - like your recovery phrase

• NEVER screenshot QR codes or save them online

---

💼 Crypto Wallet Safety

✅ Best Practices:

• Don’t store large amounts on exchanges

• Use hardware wallets (cold wallets) for long-term storage

• Verify all details on your wallet screen before confirming

• Be cautious of malware that swaps addresses — double check recipient address

---

🔑 Private Keys: The Most Important Thing

• Write down your keys on paper or metal backups (fire/waterproof)

• NEVER save private keys:

  • Online

  • In your phone

  • On cloud services

• Don’t share keys with anyone

• Beware of giveaway scams asking for keys

If someone asks for your private key — it's a scam. No exceptions.

🧠 Final Thoughts

Hacks are rare — most losses are due to user error, phishing, or negligence.

Remember:

• Cold wallets are unhackable unless you give away your private keys

• Security is not a chore — it's your opportunity to have peace of mind

Think critically. Stay informed. Protect your future.
