whether that means starting now and sorting things out along the way or wait to prepare better.
The idea of waiting to prepare better is good if only you have not sorted out your Discretionary income then you can wait to figure it out before you can proceed with your bitcoin investment but if your Discretionary income is been sort out i think there is no need waiting further as you can start buying bitcoin the earlier you started the better for you as waiting can come with several challenges of not starting when you had the chance or the opportunity to get kick off as you might get discouraged and end up making a postponment or keep on procastinating and never getting started as the more you keep waiting the more you keep missing out some good buying opportunity.
If you have a discretionary income, there is no obstacle to investing in Bitcoin with that money. It will not be easy for those who learn about Bitcoin and are encouraged to invest in it for the long term. Because they will not be able to maintain that investment. Discretionary income should be used in investing in Bitcoin. In this way, an investor can deposit Bitcoin for the long term. However, he must also keep at least 3 months of expenses as a reserve fund so that he can hold his Bitcoin despite any unexpected events. It will be easy for those who plan for the long term if they are well aware of these two issues.
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. So I think there should be a slight deviation of focus from discretionary income 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.
