The best way for a steady income, especially when it comes to Bitcoin, is to probably join a signature campaign and always cap out whatever the maximum number of posts a day/week/month is, that way you get a relatively simple and consistent income directly in Bitcoin. Now that doesn't fit your criteria of not doing anything, so that's out of the question.
One potential idea is investing in a casino bankroll and get paid that way. I haven't done it in the past but with enough research I think you'd probably have a good idea of how it would all work.
