I'm gonna be running tests for a while. I'll try to keep them in this stupid thread. Please forgive me. Plus I should be going to bed soon. This has been an incredibly harrowing day, and for some reason now I'm trying to fix my strfry router.
I both respect, and question all the people destroying their #ColdCards.
Respect because it is pure. And it is cathartic. And it is certainly a safe path forward assuming you have backed up any important secrets it might still hold.
But I question because... this hardware is well designed, and the software features and architecture are quite good.
I believe most futures for the ColdCard end with a reasonable decision to : SHOOT HERE!
But... there is this one perfect world still possible.
CoinKite chooses to fully (really) Open Source the hardware AND software. Perhaps they can continue to go on selling and supporting the device if they somehow survive the next while. (LOL)
But this scenario would allow the community to pick up and develop for the hardware.
And in this case you might regret having dropped your ColdCard into a volcano?
Calling the 12th (or 24th) word in your mnemonic seed"the checksum" is technically incorrect. It also contains 3 (or 7) bits of your base entropy. The checksum is only the remaining 8 (or 4) bits.
