- Centralized control (e.g., FTX collapse demonstrated risks)

Cold Wallets
Definition: Offline storage where private keys never connect to the internet.
Types:
- Paper Wallets: Printed keys (rarely used today)
- Hardware Wallets: Dedicated devices with encrypted key storage
Why Hardware Wallets?
- Private keys remain isolated in secure chips
- Immune to remote hacking attempts
- Typically support multi-currency storage
