Private key management is the biggest risk for average users because losing or exposing a private key can lead to irreversible loss of funds or data. Unlike passwords, private keys cannot be recovered if lost, and if stolen, they grant full access to assets on a blockchain. Most users lack the technical expertise to securely store and handle keys, often resorting to unsafe methods like storing them on unsecured devices or sharing them inadvertently. This makes them vulnerable to hacks, phishing, or simple errors. Proper management requires robust security practices, which many find complex and intimidating.
