"This Coldcard incident is absolutely suffocating—a group of people who believe in BTC's core values ended up being hurt the most. You're a BTC hodler. You've been practicing self-custody for the long term. You don't trust exchanges. You've kept your seed phrase safe and offline. You chose a Bitcoin-only, old-school hardware wallet that's been securely operating through multiple BTC cycles and trusted by many OGs... You thought you'd considered everything thoroughly and avoided all risks. But you never expected the issue to arise from the most fundamental layer: random number generation. This problem has existed since 2021. Due to a random number generation issue in certain versions of Coldcard firmware, the randomness relied upon to generate private keys was insufficient, allowing attackers to calculate and recover private keys. This is the harshest lesson in Bitcoin self-custody: whether your BTC is safe doesn't just depend on whether you've protected your seed phrase. It depends on the entire chain: random number generation, hardware wallet firmware, backup and private key management solutions, daily usage habits, and security awareness... Self-custody isn't as simple as "buying a hardware wallet and transferring your coins into it." A hardware wallet ≠ absolute security. Bitcoin gives us ultimate asset sovereignty, but it also requires us to take full responsibility for that sovereignty. The Coldcard incident triggered the migration of approximately 77,400 dormant BTC on-chain—the largest on-chain migration since the FTX collapse. Some people are reconsidering moving BTC back to CEXs or buying ETFs, giving up self-custody, and that's truly regrettable. #Bitcoin #BTC #Coldcard #SelfCustody
