You are too advanced. I use Trezor as my cold wallet but working on a project to install Umbrel in Ubuntu in a Thinkcentre mini PC. I want to connect my Trezor to it. Also I would like to install a keet.io relay to chat with family and friends. Next I would like to learn more about the LN to setup a LN node. And of course I want implement a nostr relay. I will be entertained for a while as I'm not that computer savvy.

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.
