    title: It seems people did not understand what happened to ColdCard
    body:
    Self custody is not a problem, what happened is that generating your seed with a ColdCard MK3 would not have enough entropy, making your private key easy to be guessed, thats it. Your MK3 is still usable, but you should NOT use it to generate a seed, instead you have to use any other solution to generate your seed and then load it on your MK3.

    Your MK3 is not useless, it still works as intended.

    You really shouldn't use any of these "solutions" to generate seed. They all could be vulnerable to the same issue. Use dice instead.

    if you take an actual look at iancoleman solution, it provides you entropy options, and dice is there, as well as binary, Base 6, Base 10, Hex and Card entropy.
