Protecting crypto requires five defenses: secure your identity, choose custody deliberately, verify every signature, monitor exposure, and prepare a recovery plan. A hardware wallet alone…

A seed phrase is an ordered set of recovery words that can recreate the private keys for a compatible crypto wallet. Anyone who sees it may be able to control every account derived from it,…
