Is Rolling Your Own Entropy The New Standard? (Coldcard Q&A P1)

<p>In this Guy's Take, I walk through listener questions and comments on the Coldcard random number generation failure and what it really means for Bitcoin self-custody. We dig into why the RNG bug went unnoticed for years, the difference between source-available and truly open source hardware, and how dice rolls and strong passphrases change your threat model. I also share how I’m thinking about safer setups going forward.</p>
