Steady income can be achieved by many ways but according to me i am quite sure that its not possible with bitcoins right now, These days due to lot changes in rates makes the trading unpredictable.
Having that opportunities to join the signature campaigns here served as a steady income for us and I think it became sustainable as time goes by so future investments and jobs that we have here can be a better options to have. It's so hard to find physical job nowadays so with the help of bitcoin to be the most sustainable and physical work free this is the best steady income which I can recommend to everyone.
