#CryptoSecurity101 Here's a **comprehensive Crypto Security 101 guide** covering essential practices to protect your digital assets:
### 🔑 1. Master Key & Seed Phrase Security
- **Seed Phrase = Your Crypto**: Treat these 12-24 words as literal cash
- **NEVER** digitalize: No photos/cloud/email/text/typed docs
- **Physical backup only**: Use fire/water-resistant metal plates (e.g. CryptoSteel)
- **Zero sharing**: No support rep will EVER ask for it (scam!)
### 💻 2. Wallet Protection
- **Hardware Wallets**: Use Ledger/Trezor for significant holdings (>$1k)
- **Software Wallets**: Only official apps (double-check URLs!)
- **Multi-Sig**: For large sums (>$50k) require 2-3 signatures
- **Dedicated Device**: Use separate phone/computer only for crypto
### 🛡️ 3. Transaction Hygiene
- **Triple-check addresses**: First/last 4 chars + middle section
- **Test sends**: Always send small amount first
- **Reject "too good" deals**: Free token claims = 99.99% scams
- **Revoke unused permissions**: Use revoke.cash regularly
### 🌐 4. Digital OPSEC
- **Separate emails**: Crypto-only email (ProtonMail/Tutanota)
- **2FA**: Always! But **never SMS** - use Authy/Google Authenticator
- **Password hygiene**: 12+ chars, unique per service, password manager
- **VPN**: Always on for crypto activities

- **Fake support**: Anyone DMing first = scammer
- **Malware**: Never download "wallet updates" from email
