ColdCard Hack Deep Dive: Is Your Self-Custody Actually Safe?

Hey Bitcoin Bay Community! 🍁 Canada’s longest-running crypto community is hosting a special, high-priority meetup to address the recent ColdCard hardware wallet vulnerability. **The Context:** On July 30th, a critical flaw was exposed in the Random Number Generator (RNG) and entropy collection of certain ColdCard devices during initial wallet generation.
