Coldcard Wallet Incident Highlights the Growing Threat to Bitcoin Self-Custody - Tekedia

More than 500 BTC were reportedly stolen from Coldcard hardware wallet users, raising fresh concerns about Bitcoin self-custody security.

Investigators are looking at phishing, supply-chain compromise, malicious firmware, or seed-phrase exposure rather than a direct hardware flaw.

The incident shows that hardware wallets alone are not enough and that user operational security remains a major risk factor.

As self-custody adoption grows, device verification and user education are likely to draw even greater emphasis.
