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!
I wouldn't recommend anyone to use Tangem or Coldcard devices because they are both closed source black boxes.
You can import seed words to any other hardware wallet of your choice (if you didn't expose them before) but I would strongly recommend using open source devices like Trezor, Passport, Keystone, etc.
