Trezor, Onekey, Bitbox Sales Spike Amid Coldcard Crisis; Security Models Evolve

A recent Coldcard crisis over security and trust issues prompted users to pivot to alternatives, driving sales spikes for Trezor, OneKey and BitBox. The market response reflects a broader shift in user preference toward diversified hardware models, open-source firmware and clearer threat-model communication. For Bitcoin this accelerates ecosystem resilience by reducing single-vendor concentration, raising scrutiny of device security, and likely spurring faster innovation in custody solutions.
