Is my understanding correct one the following wrt coldcards:
1 - a wallet with a good passphrase added makes you safe
2 - sufficient dice rolls, even with slightly biased dice (lol?) makes you safe

1. About as secure as the passphrase. So, somewhat harder than a brain wallet to crack. (Unless you used truly random words)
2. Yes. You can just add more rolls anyway
Re:dice, my understanding is it sha256s them, so it really serves as a random seed for that algo, hence bias not too big a deal if you roll plenty (saw peter Todd post something on c along these lines)
