Asking for a friend:
If someone has a cold card. They only ever set it up and moved their whole stack to it. Said stack is mostly KYC'd. Can this same cold card be used for a separate, non-KYC stack without the one giving away the other?
Does this question make any sense?
In theory, it should be possible as far as network privacy goes, but you may want to keep it separate just for simplicity and/or if an adversarial entity forces you to show the device with the KYC coins.
if you use 2 bip39 passphrases, it will map to 2 different xpubs.
I recommend you read coldcard's documentation and/or look at nostr:npub1rxysxnjkhrmqd3ey73dp9n5y5yvyzcs64acc9g0k2epcpwwyya4spvhnp8 video tutorials.
It’s very possible. You can also create hidden or false wallets on the Coldcard (to prevent attackers from seeing non-KYC stack)
Yea just use a different passphrase
