Try to learn trading instead of gambling, in trading there's a lot of strategy that you can learn in just a easy way unlike gambling this game just making you a greedy on the money, trading can be a source of income a steady income aside from it you can just focus here in btctalk.

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.
I also find signature campaign as one of my source of bitcoin. Because for me the best way to get into bitcoin is to find a way to educate yourself in regard to different things about bitcoin. And one of the best thing is to try on reading in bitcointalk where you can read topic about bitcoin , trading and investment and you can earn at the same through signature campaign where you need to post to earn. And then used your partial earning on trading or investment for more income.
Signatures come and go, there is nothing steady in this.
People looking for steady income should look into stuff that have a contract a clause and terms not just and agreement made with two posts on a forum.
There is nothing steady around here, trading is a gamble, mining is just as steady as the difficulty and most of the other jobs are just temporary.
