Cryptocurrency empowers you to be your own bank through "self-custody"—the practice of safeguarding your digital assets using crypto wallets. This guide simplifies wallet types, security best practices, and key terminology for beginners.
Essential Crypto Wallet Terminology
- Private Keys: A long alphanumeric string acting as your wallet's password. Never share this—it grants full access to your funds.
- Recovery Seed Phrase: 12 or 24 randomly generated words that restore wallet access if your device is lost. Store offline and never digitize.

Types of Crypto Wallets Compared
1. Hot Wallets (Software Wallets)
- Connection: Always online
Pros:
- Instant access via apps/extensions (e.g., MetaMask, Trust Wallet)
- Free and user-friendly setup
Cons:
- Higher hacking risk (private keys generated online)
- Less secure for large holdings
2. Cold Wallets (Hardware Wallets)
- Connection: Offline storage
Pros:
- Immune to remote hacking (e.g., Ledger, Trezor)
- Ideal for long-term holding
Cons:
- Requires physical device purchase (~$50–$200)
- Less convenient for frequent trading
| Feature | Hot Wallets | Cold Wallets |
|---|---|---|
| Security | Moderate | High |
| Access Speed | Instant | Requires device |
| Cost | Free | One-time fee |
3. Exchange Wallets (Custodial)
- Risk: "Not your keys, not your coins" — exchanges control your assets (e.g., Coinbase, Binance)
- Warning: Vulnerable to exchange collapses (FTX, Celsius)
