In crypto, your digital wallet is only as secure as your habits. Use a hardware wallet for large holdings, enable 2‑factor authentication everywhere, and keep your software updated. Store seed phrases offline and in separate locations, avoid public Wi‑Fi, and watch for phishing emails. A multi‑sig setup adds an extra layer of protection. Stay vigilant and keep your assets safe.
