The Biggest Lie Bitcoin Investors Are Told In 2026 ( Not What You Think) | Matej Zak

Deep dive into hardware wallets, self‑custody and evolving threats—AI phishing, quantum risks—and practical security, backup, and product design lessons from Trezor’s team.

Key Takeaways

Self‑custody matters: exchanges are honeypots; start with software wallets, then move to hardware for stronger key protection and offline signing.
Threat landscape: AI‑driven phishing and social engineering are escalating now; quantum computing is a future risk—plan updates and adopt post‑quantum defenses.
Device security: prefer auditable, open‑source secure elements and dual‑secure‑element designs; privacy‑by‑design and no‑KYC models reduce data collection risks.
Backups & recovery: keep BIP39 seed phrases fully offline, use metal or paper backups, store geographically dispersed copies, and consider threshold share splitting or multisig.
Physical hygiene: never advertise holdings, buy only from official or authorized resellers, verify packaging/firmware, and avoid previously handled devices.
Usability vs security: include on‑device displays to prevent blind signing, design upgrades that reduce human error, and target users who need cross‑chain, advanced features.
