I agree, although your phone may not earn a stable income to pay for essentials, there is some potential to earn. I'm not a young person, not far off 60 yrs old and already have a very small pension, and any independent income gets me off welfare assistance, which I hate being on. In all honesty, with ageism and the long time I've been out of work, it's unlikely I will get a "permanent" steady job, so creating my own passive income is ideal.
