Have you tried checking what the bytecode does? Maybe it's just a way to block detection by Microsoft and antivirus programs, by creating a different binary every time. Just because something isn't written in a high level language doesn't mean it's malicious. But it may be.
I use it and like its UI but it doesn't properly support offline, you can just download single tracks. By proper offline support I mean something like Audinaut, which unfortunately doesn't work in new Android versions
Blik only works on smartphones inside banking apps. You can't just generate the codes on the bank's website. Don't fall for it, it's one more step towards bank fueled totalitarianism. I have no idea why it got so popular in Poland.
I used google ads with very specific phrases and geolocation limited to rich countries. I spent a lot on it, the sales were like twice of what I spent, but I got some good contacts from it and they kept coming back for more.
But, and that's a big "but", I was employed before, noticed a niche that no commercial provider filled, and created my product. It wasn't an idea that I thought was fun or could change the world.
I like to leave ssh over tor hidden service on remote boxes. It's pretty resilient and can serve as emergency access for when something happens to the VPN. Not a great primary access method because of the latency.
When i was young the water method worked but that was a long ago, it all gets fucked up later in life. I was among the first in my friend group who had killer hangovers, and by the time we reached 40 almost everyone told me something along the lines of "now i know how you felt".
I did not, actually, because it's behind a paywall. I've linked and read another one in the comments but it fails to mention about post offices and says the money is going to customs.
Tough audience here, huh?
