A sobering one for the self-custody crowd. A software bug in Coldcard, a widely trusted Bitcoin hardware wallet, made seed generation predictable enough that attackers swept roughly 594 BTC (about $38M) from around 500 wallets, no phishing, no leaked key, just weak entropy at the source. Your wallet is only as safe as the randomness behind your seed. The uncomfortable takeaway isn't "self-custody is bad," it's that self-custody moves the risk, it doesn't erase it. The same stretch we watched a bridge and an oracle fail, a hardware wallet's key generation did too, all of them the infrastructure around the cryptography rather than the cryptography itself. This will push some users toward ETFs and custodians, a real tradeoff, not a free lunch. Security is a discipline, not a device. Verify your entropy, diversify your risk, assume nothing is bulletproof. NFA. #ColdcardBTCExploit #OKXOrbit
