To safely store cryptocurrency, ordinary users can choose between cold and hot wallets. **Cold wallets** (e.g., hardware wallets like Ledger or Trezor) are offline, offering high security against hacks but less convenience for frequent trading. **Hot wallets** (e.g., mobile or web apps like MetaMask) are online, user-friendly, but vulnerable to cyber threats. For maximum safety, store most funds in a cold wallet and use a hot wallet for small, regular transactions. Always back up private keys securely.
