Here’s some info on dice and entropy, and how easy it is to do a saltwater test (verify fair dice) https://bitcoinistrue.com/saving/appendix/dice/

On Coldcard: For years self-sovereignty minded Bitcoiners warned against hardware wallets. Although I’m honestly shocked that the vulnerability was a bad random-number-generator, from someone who should know better. Understand the first principles of self custody and it becomes very clear that HWWs are a dead end. No talk of “secure element” means anything if you start with the first principles of securing your keys. “Use dice” and control your own entropy. It’s cheap, your biggest risk is “loaded dice” and you can prove cheap plastic dice are fair with salt water. And there’s many other sources of entropy. What’s fascinating is that this entire ordeal feels like a blast from the past, something that should have happened in 2022. But now it’s making big news in the remnant of those who still care about Bitcoin self custody, and yet has demonstrably zero impact on the market, something that would not have been true years ago. This is honestly the bigger takeaway. I expect there will be more of these. I’m almost kicking myself for not pointing an LLM at open source hardware and software and looking for weak sources of entropy… I’m still surprised Satoshi’s “lost” Bitcoin was never retrieved with such methods.
