🚨 $70M Gone, Zero Warning — The Real Lesson Isn't About Coldcard Galaxy Research just revised the damage upward: 1,082.65 BTC (~$70M) drained from 1,196 wallets in 41 minutes — nearly double the first estimate. No phishing. No malware. A firmware bug from 2021 quietly broke the randomness behind these wallets' private keys, and years later, someone rebuilt the keys offline. The real lesson: this is a money management failure, not just a tech failure. Every one of those 1,196 wallets made the same mistake — concentrating everything in a single point of failure. Doesn't matter if that point of failure is one exchange, one hardware brand, one firmware version, or one seed phrase. The math is the same: 🔐 One basket = one bug, one bad actor, one mistake away from zero 🔐 Split holdings = a single flaw caps your loss instead of wiping you out This is the same principle behind not putting your whole portfolio in one asset, one exchange, or one strategy. Self-custody doesn't exempt you from it — if anything, cold storage users are the ones who assume they're "safe enough" to skip this step. Practical diversification looks like: ✅ Multiple hardware wallet brands (not just multiple devices of the same one) ✅ A mix of self-custody and regulated custodial options ✅ Multisig setups where no single key/device can move funds alone Even CZ flagged this after the incident — but it's not a hot take, it's basic risk management applied to crypto. Bottom line: "Not your keys, not your coins" is still true. But "all your keys, one wallet" was never a safe rule to begin with. 👇 How do you diversify your holdings — multiple wallets, multisig, or a custodial/self-custody split? #ColdcardFlawDrains594BTC #CryptoSecurity #cz
