BitBox02 Bitcoin-only edition
Key features
Supported coins
Supports only Bitcoin
For multi-coin support see BitBox02 multi-coin edition
It is not possible to convert a BitBox02 Bitcoin-only edition into a BitBox02 Multi edition or vice-versa. The BitBox02 bootloader prevents firmware downgrades and installing firmware for a different edition of the BitBox02 (Multi or Bitcoin-only) as otherwise that would be a security attack vector.
