A steady income from bitcoin untu now is
1.Trading
2.Faucet
3.SIgcamp (in this forum)
I think all three can give every day our income, other than it was a gamble but it could not count on because it is not every time we win a bet
i'm in doubt to call those steady income, you have trading which is not steady there is a high risk and you can lose everything, you have faucets that give you few cent and are not worth it imho, and finally you have signature which is the best but you need many alt that join more signature and the risk is the ban of your account, the best for me would be mining
