Security Guide
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?
🚨 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

🔐 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.
