200: Coldcard Catastrophe

The Bit Bite Podcast

About

Ep200 In this episode, we break down one of the biggest hardware‑wallet failures in Bitcoin history. Coldcard’s backup randomness system secretly produced weak seeds for years, allowing attackers to guess private keys and drain over 1,000 BTC in minutes. We explain the catastrophe in simple, 5th‑grade‑level language, walk through what happened, why it happened, and what listeners should do right now if they used a Coldcard during the affected period.

We also cover whether other hardware wallets are safe, the difference between open‑source and closed‑source security models, and how third‑party auditors help prevent disasters like this. Finally, we update you on the latest movement in the CLARITY Act and what it means for everyday crypto users.

A must‑listen for anyone securing Bitcoin in 2026.
