that's an entirely plausible number. Many people dance that much after work for fun, for free.
why wouldn't you take 5$ donations on paypal for it? 
that's basically what streamers do. Many streamers make even more than that a month and do shit all for their audience, the audience is entirely passive. 
most donations to streams are for streamers to do shit for you: should you out, sing you a song, what the fuck ever.
it's not really all that different.
