I think there's need to look into the concept of Discretionary income in bitcoin investment and how it relates to stable source of income. I don't think that someone who does not have a source of income can actually have a real discretionary income. Discretionary income is that fund in which the owner does not necessarily need at that period or over a period of time before his next income.

In the event of believing that discretionary income exists when someone does not have a stable source of income is somewhat deceitful. This is because what seems to be discretionary income today, maybe because of a given lump-sum that gets into the hands in a given person. In that case, I don't see it as a discretionary income because since there's no hope as to when next such a person would see such income or any money, he would definitely exhaust the entire money and if he had invested a part (supposed discretionary income) into bitcoin, he would have no other option than to sell off his bitcoin at the end to sustain himself.

I strongly recommend having access to stable source of income to which you can envisage your next income before you can refer to any part of the fund and discretionary income because you would always have a cushion after a period of time.  to Having a stable source of income first. This is the only possible means of investing and successfully holding for long since he would also have a source of emergency funds and back up funds saved simultaneously.
