Crypto hardware wallet comparison BitBox02 Bitcoin-only edition vs Trezor Safe 3
Our impressions
BitBox02 Bitcoin-only edition
Trezor Safe 3
- Small form factor and very portable
- Excellent value at an affordable price point
- Phenomenally intuitive and efficient on-device recovery, PIN and seedphrase entry
- Requires constant USB connection to operate
Finally the first line of Trezor products incorporating a secure element has arrived. In our opinion it easily takes the lead in the current Trezor product lineup – in terms of security and portability. Even with the launch of the newer Trezor Safe 5 it’s easily our price/performance winner.
Even though the device uses only two buttons for input, like the Model One did, and does not offer a touch-screen, like the Model T and Safe 5, its on-device recovery, PIN and seedphrase entry are phenomenal. Trezor really did something truly special with the way they handle user input despite the minimalist form factor. At less than half the price of the Trezor Safe 5 it is an easy recommendation.

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.
