I'm about to switch from a Tangem wallet to a Coldcard Q. Tangem was my first ever HW wallet, so I don't have any experience "changing wallets". Is it better practice/security to generate a new seed phrase with the new wallet, and then send my BTC over from Tangem (testing with a smaller amount of course), or should I just restore my seed phrase from when I created the Tangem wallet? Appreciate any input, thanks!
Restoring your crypto wallet using the seed phrase on the Coldcard Q will make the replacement from a Tangem completely meaningless and in your case, the best solution would be to transfer the contents of the Tangem wallet to a new created wallet on the Coldcard Q. That is, generate a new clean seed phrase on Coldcard Q, to which all your cryptocurrencies will be sent.
I would like to ask, what exactly is the reason for your switching from one device (Tangem) to another (Coldcard)?
And what will you do with Tangem? After all, you can use this wallet to store a small amount of cryptocurrencies, for example.
