Good to know that someone can really share your posts that way even if you give accurate information. LoyceV, I suggested him to go for an air-gapped system after setting the wallet. I guess ABCbits has shared something valuable about cold wallet which I'll note from now on.
But it also contain has inaccurate information. And while we're it, could you edit your post to remove or cross-out the inaccurate information?
On the other side, I am a Linux lover and very careful when handling it, but even as an amateur, not a professional, installing an electrum wallet from Appimage seems to me to be one of the simplest things.
It's good to know that you're a Linux lover, but I don't agree that installing electrum wallet on Linux is that simple. I know if someone has technical expertise then for that person it isn't a hard task but for an armature with no technical knowledge won't be able to do that easily. On the other hand installing or running portable version of Electrum on Windows OS can be done easily by someone with no technical skills.
If you ever tried using Electrum Appimage, you wouldn't say that. Download and run Appimage (Linux) is nearly as easy as download and run portable version (Windows). Here's a very simple GUI guide,
