In the world of cryptocurrency, security is fundamental. Unlike banks, there is no "undo" button in case your money is stolen. Start with the basics: use strong and unique passwords, and enable two-factor authentication (2FA) on all your accounts. Never share your private keys or seed phrases - anyone with access can drain your wallet. Prefer using hardware wallets for large amounts and avoid clicking on unknown links or connecting to suspicious decentralized applications. Be cautious with airdrops and free giveaways - many of them are phishing traps. Whether you are trading, staking, or holding, your security habits are your first and last line of defense. Stay alert, stay safe.
