Coldcard MK4 vs BitBox02
Key differences
- Coldcard MK4 is fully Bitcoin-only with advanced air-gapped options and keypad input; BitBox02 supports Bitcoin and 1,500+ tokens with simpler plug-and-play usability.
- BitBox02 is more compact and beginner-friendly with touch sensor navigation, while Coldcard is better suited for experienced users focused on offline self-custody.
- Both have dual-chip security and open-source software, but Coldcard emphasizes physical separation and microSD backups, while BitBox02 offers convenience through USB-C and multisig compatibility.
