The X post by @notgrubles expresses deep pessimism about a potential "scorched earth" threat to Bitcoin's hardware wallet ecosystem, triggered by Coinkite (makers of Coldcard), whose reputation was devastated by a major 2026 firmware entropy bug. The bug, present in certain Coldcard models since 2021 firmware, bypassed proper hardware randomness during seed generation, allowing attackers to brute-force weak seeds and drain roughly $38-100+ million in BTC from hundreds of air-gapped wallets in minutes. This failure of a once-trusted Bitcoin-only device has accelerated shifts toward exchanges, multi-vendor multisig recommendations, and widespread doubt that any single hardware vendor can guarantee self-custody security. -GroK
