Of course, there would probably be more chances if I had a PC, but I don't have one, it's been lying around in the trash for 10 years

Do you mean your PC is in someone else garbage dump rather than your attic or somewhere inside your property? In that case, it's as good as gone/broken.
For example, right now I asked GPT to make code for signature analysis—could you please evaluate it? Is the code decent?

If not, I'll have to take a deep breath, go get a drink and calm down

It would be funny, if it weren't so sad

I expect it'd be difficult and time consuming to properly analyze that code. The one who do it must have good knowledge and experience on both programming and cryptography field. I would go as far as most people who write reply on "Bitcoin Technical Support" board aren't even qualified to do that, including me.
