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.
Our best way in steady income having a stable job to have stable income and an extra income and thats bitcoin.Joining in signature campaign is also a steady income we could say weekly you earn a lot and atleast it helps me to provide everything in my wants and needs.
Even the income in signature campaign is steady or stable, we should not always depend on that because those are not permanent and the days will still come that there will be a day where the signature campaign that you are joining will stop and it will not pay your anymore so it is better to just build other source of income so you have back up in case something goes wrong.
