The reverse of this situation becomes the best approach, that is to say it is most important that one should first prioritize taken care of your basic needs that's your living expenses then the left over cash, the remaining money(discretionary income)is meant to determine how much you put in to your investment. If you don't prioritize your living first there is every possibility that you might used more than what is meant to be used for your investment to accumulate Bitcoin and will increase the risk of selling your Bitcoin too soon to settle your living expenses.
True. Does that mean that investment is not for everyone even when you have the interest and got little resources to take care of yourself? At what point do you think one should have the capacity to be able to invest his money. Because for me and for the country where I live, due to the high inflationary economy of the country and the very high standards of living, you can barely have something to save or channel into investments because of the uncertainty that the economic situation comes with. If you say, you're going to wait until you have extra funds, then you might end up waiting forever unless you're extremely comfortable with good money, which is difficult.
Take myself as a case study, I come from a community and family which is not doing so well hence my responsibility to cater for some of their needs to be able to have peace of mind and comfort. By so doing, you're tied in a situation where you have to feed yourself and still feed some people around, barely having some extra funds to invest. Does it mean one cannot also invest in crypto? Please I need some piece of advice here.
If your income cannot gove you the extra funds to invest, you should get a second means of income and cut down your expenses. When you have a second means of income, that can be used as your extra cash which you can use part of it to invest on bitcoin. Life is not easy but with proper plans and looking for ways to boost up your income will make life not as difficult as it ia for you.
I don't think that not having a discretionary income is an excuse for anyone that is willing and have the passion to invest in bitcoin for his future, because he knows that bitcoin can change his financial situation in future if he is able to accumulate a good size of bitcoin in future. I could remember when I was in your shoes, and my income hardly take care of needs talkmore of having extra cash. I had to look for various means of income, and I got a second means to add to my first income and I overcome the problem.
