you are far move advanced. you have a non proprietary hard wallet. Lightyears ahead of most of these grasshoppers out there! I would never trust a hardware wallet that has their designs secret. Although cold card has open source software, its hardware is copy protected and closed source. Trezor is fully open source hardware, firmware and you can use it with open source software wallets like Sparrow. You can literally print a trezor on your own if you have a 3d printer. The choice is clear for me. I dont trust anything that operates in secrecy without transparency.
