For steady income anything with bitcoin is not possible i think. I suggest you find lower risk investment, such as 510% interested, and live off the interest. If you invest like $100k then it is $5,000-$10,000/ year. Bitcoin is risky. I dont think that bitcoin can provide you with steady income. It's always fluctuating.
The volatility of bitcoin will either give you more profit of huge losses. If you will use bitcoin as a form of investment so you can get a high return then you must have a long patience attitude to wait for the right moment when the price of bitcoin increases and to never panic when its price decreases. Bitcoin is very risky and it will never give you a steady income unless you will also do some business activities such as trading and others to increase the number of bitcoin at your disposal.
