For some teenager this all may seem ok, it may be a great fun purchasing BTC in the middle of the night, but I am a normal guy who actually works for a living, who occasionally trades stocks or bonds on market for other normal, working guys like me and this is a completely shocking, unacceptable experience.
Are any people with similar background and experiences on this forum and what can you, please, recommend to me?
Unfortunately the only recommendation that's actually going to solve your problem is "Leave the US". I am not making this lightly and it is not a joke: the reason you can't get Bitcoins like the civilized world can is that your government has decided you are some teenager. Each and every single US citizen. In that context, your hope that you're a normal guy is misplaced: you can't be. It's the law of the land over there.
If for whatever reason you can't or won't quit the kindergarten/prison/cattle ranch, you will have to come to terms with the cold reality that US regulation has in fact turned the entire US into a banking ghetto of underserved people (a customer of US banks you are not) and dysfunctional mechanisms. Consequently, you will have to stay up nights, you will have to come up with clever "crack in the wall" solutions to get actual BTC much like the "normal guys" who weren't teenagers by age but happened to live in the Soviet Union had to stay up nights and come up with weird plans in order to acquire toilet paper thirty years ago.
I understand your frustration, but it's entirely misdirected. Move to an actual country, you're not in one.
