Hot Wallet vs Cold Wallet: Hot wallets (like MetaMask) are convenient for transactions but come with higher risks, suitable for small daily use; cold wallets (Ledger/Trezor) offer more security with offline storage, ideal for long-term storage of substantial assets. I adopt a combined strategy: 5% of assets in a hot wallet (DEX trading), 95% in a cold wallet (stored across 3 hardware devices). Core of security management: 1) Physical backup of cold wallet mnemonic on a titanium plate; 2) Hot wallet only connects to verified DApps; 3) Regularly check contract authorizations (revoke.cash). Security practice recommendations: ① New users should start with a cold wallet to learn basic transfers; ② Use a multi-signature solution (like Gnosis Safe) for substantial assets; ③ Be cautious of phishing sites (always manually enter the URL). Key principle: Security and convenience are always inversely proportional and should be dynamically adjusted based on asset scale.
