By holding BTC you already have steady income as the value increases 
Other way is: you put a large sum of money in the bank and convert the interests to btc. But in order to make any significant income, initial sum should be really big.

I don't really agree of this thing. Holding a bitcoin is not considered as a steady income it is belong to investment.Because base of my research there was a inflation and deflation happening in bitcoin.It's seem you already know this I think you just forget.If you want a steady income then you find a stable job that fits onto you and also you had passion of that work.
