How much can you earn by showing your private life online? I mean live voyeur cam, area of webcam business. Do you think it's worth trying to make money from it?

As far as I understand it, this kind of work is done by people who have a natural inclination to do it. That is, they do it more for pleasure than to make money. With live voyeur cam business you can also make good money, but I think that classic webcam is more profitable. In general, you'd better find webcam model forums and ask this question there.
