Types of Crypto Wallets

Applications on your computer or phone. Good balance of security and convenience.

✓ Easy to use ✓ Good for daily transactions ✓ Many features

⚠ Connected to internet ⚠ Vulnerable to malware

Wallets managed by cryptocurrency exchanges. Convenient but you don't control the keys.
