The point is like this, having a stable income does not guarantee that someone will have discretionary income. Because it could be that even though the income is stable, the nominal amount is not too large and is only enough for daily needs (so the point is not having leftover money or discretionary funds). So having a stable income also cannot guarantee that someone can invest in bitcoin. But if people have discretionary income, it is certain that the person can invest in bitcoin and it can also be concluded that the person's income is quite good, because they have leftover money. So which of these two assumptions is correct, in my opinion the most appropriate is that people who have discretionary income can invest in bitcoin safely. Because the point is the important point is in their discretionary income, when it comes to income, it's up to you, whether it's stable or not. Because there are quite a few people who have unstable incomes, but when they have income, the amount of money they get is very large.
The important thing is not necessarily that your income is steady or not but whether there is something left over after taking care of your essentials. There are those who have monthly income yet still find themselves caught in a pay check to pay check lifestyle and there are also those who have an irregular income yet they are able to save and invest wisely. Well it would be best to wait till you can have some more space in your budget to invest in Bitcoin, than to endure basics by straining.
Low coiner is better than no coiner provided you are consistent and smart about it.
Yes, to invest in Bitcoin of course all our needs must be met, because if not met of course the investment will be problematic and not ideal. Therefore, before being able to invest, we must be able to increase our income and perhaps reduce our living expenses. By doing these two things I think anyone can invest in bitcoin. Although it is basically not easy, but everything related to investment of course should not be done when we are not yet able to do it. So to be able to invest we have to fight hard to be able to make it happen. And what you said about low coin yields, if what you mean is altcoin, I think it will only make us even worse. So the point is like this if you can't invest in bitcoin, don't force yourself to invest in altcoin. Because even though the price is cheap but it has a super high risk. So with that, it's better for you to be patient first and not be reckless. So the point is if we are not yet able to invest in bitcoin, then look for a large enough income so that we can have discretionary income. So the point is don't take unnecessary risks.
Your post is very okay but your last statement is what I don't really agree with because one doesn't necessarily need a large source of income first before they can start Bitcoin investment because different individual have different level of needs and wants that is to say that some folks needs and wants maybe high or big while some folks need maybe very small, in this case someone with little needs and wants don't really need those large source of income before they can start although large source of income is really good if one actually knows how to make use of it because some folks are wealthy yet no improvement in their investment.
