If you are someone who believe that they are not so smart around Linux like myself it's better to avoid Linux OS all together, some are stronger than the other but that's not even why I am talking about this.
Some people are just too dumb to handle Linux OS especially those with advanced distros, you installing new things that comes your way can get you malware still.
https://www.reddit.com/r/cachyos/s/Ogx4QQEemPSome time ( not too long ago ) Red hat had an incident whereby Devs are losing their credentials, I don't know if anyone else noticed this incident?
While some people will say that AUR is not the main Arch packages respiratory ( maintained packages) there are so many users who can't even tell the difference.
Attacks and malwares are possible on Linux OS, make sure you understand what you are getting into, this is the only way that you can protect yourself and also every crypto wallets you stored on any Linux OS, atleast understand what you are entrusting your trust to.
Something that's made from scratch for one purpose only ( like hardware wallets ) is always better than something that was made from scratch for many things.
