#CryptoSecurity101 Security in Web3 is critical due to its decentralized nature and direct management of digital assets. To safely store cryptocurrencies, use hardware wallets to keep private keys offline, minimizing hacking risks. Never share seed phrases or private keys and enable two-factor authentication (2FA) on exchanges. Beware of phishing scams and always verify website URLs. Regularly back up keys and keep software updated. Consider using multisig wallets for transactions requiring multiple signatures to enhance protection.
