Before you choose

Consider

Blockstream Jade ClassicA small screen with wheel and button controls. QR signing needs a compatible app; Liquid uses USB or Bluetooth.

BitBox02 NovaOn iPhone and iPad, Bluetooth carries the data but the wallet still needs a physical power connection. You control it by touching its edges, not the screen. BitBoxApp on iPhone and iPad guides firmware updates when a compatible version is offered.

Block BitkeyTwo of three keys are needed. Recovery involves your phone, cloud storage and the service, rather than a conventional recovery phrase.
