#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

### 🚫 5. Scam Defense

- **Fake support**: Anyone DMing first = scammer

- **Malware**: Never download "wallet updates" from email

### 🔍 6. Verification Habits

- **Website SSL**: Look for 🔒 + correct URL (no typos!)

- **Slow down**: Scammers rush you - legit ops have no urgency

### 🚨 7. Critical Rules

- **"Not your keys, not your crypto"**: Avoid long-term CEX storage
