Is dancing marketable, where a person make use of it as a source of his income?

Yes, because you can go to college to become professional dancers. You can for videos and some movies and for all these things you get paid for.

In my opinoin, or the way I see it. If you make your own dance class or dance studio and get paid to teach dance, you could probbly make a source out of the income. But if you are just talking about dancing in general, you could maybe make it to the market.
