Just a guess honestly

Good to know, thx.

Huh, didn’t know about that. I should try the application again.

Not every applications runs in Wine. For example I didn’t get USB devices (not storage, connection to a special device) running in Wine. And I can imagine that old serial connections and so are even more tricky.

“lost”. Isn’t it just virtual money from the values of the shares anyway (until they are realized by selling)?

Proton: didn’t find anything (but I just did a quick lookup)

This is called reproducible builds. With this all builds of a version will be binary-identical. So you can build from the repo and the compare it with the appstore binary and see if the owner was honest.
