    +You can still use the device to sign transactions. Blow away any pre-existing seeds, update the firmware, do dice rolls and confirm it via separate source online to make sure the cold card is giving you the same values, repeat but don't check online and use that seed and then set a passphrase.... You should be golden.

    Now that ColdCard is probably done and the hardware is owned by people, what else can we use it for? Obviously not for storing bitcoin, but what could we use the device for? Some people say to use it as a signer, but I'm just wondering if we can use it for other things, just an idea: encrypting, for example, SD cards.

    Use it as a wedge to adjust wonky tables, door stop, fidget spinner, paper weight, I heard you can play doom on it? Loads of things you could do.

    Multi sig maybe… if you trust them even a tiny bit, I don’t. Like, they had several years to test the code, heck last year alone with all the Ai advancements, nothing.

    Reset with new firmware then key made with physical entropy, they'll still make a great signer in a multisig. 
    
    And multisig IS what you should be moving to.
