#SouthKoreaCryptoPolicy Crypto security is crucial due to the irreversible nature of transactions and common threats like phishing and malware. Best practices include using hardware wallets (cold storage) for significant holdings, enabling two-factor authentication (2FA) for all accounts, and employing strong, unique passwords. Never share your private keys or seed phrases, and always verify wallet addresses before sending funds. Regularly update software and be wary of unsolicited links or offers. Diversifying holdings across multiple secure wallets can further mitigate risks.
