Security in crypto is not optional — it's essential. Unlike traditional banking, you are responsible for your own funds. That means strong passwords, two-factor authentication (2FA), and never sharing your seed phrase — not even with "support agents." Use hardware wallets for long-term storage and avoid clicking suspicious links or downloading random files. Stay updated on phishing scams and rug pulls. Remember, if it sounds too good to be true, it probably is. Your security mindset can be the difference between growing your portfolio or losing it overnight. Stay alert, stay safe.
