How sure are you that a person without income can invest perfectly well than those that has a source of income?
You seems to have forgotten that it is through your income that you would figure out your discretionary income that's after you must have pay for your basic necessities. So without a source of income there's no way you can invest in Bitcoin talk more of to do it perfectly. when you don't have a source of income any money that comes in, perhaps from Side hustle or from your family members will be used to pay for your basic necessities, you barely see someone that does not have a source of income thinking about investment of any kind. Their focus is always centered on how they can sort Thier basic necessities. So there's no way I would agree with you when you said that a person without a source of income can invest perfectly well than someone that has a source of income, even though surely they will manage to invest but Thier accumulation journey can never move perfectly than Those that has a source of income.
Tbh, I doubt if you yourself really understand what discretionary mean coz if you do, then you would know that discretionary income can come from a whole lot of source, rather than only your source of income.. Discretionary could come from long time savings, or even pension or pocket money, side hustle, bonuses, investment return, I mean literally a whole lot of other sources to get discretionary income from... And as far as it is your discretionary income, it dosen't really matter where it comes from because you could definitely invest in Bitcoin using it...
If you read @ejikeme well you will understand his point, it doesn't seem like he's denying the fact that who doesn't have a job can also invest in bitcoin, he's talking about the ability to do it well, perhaps consistently. The truth is that anybody can invest in bitcoin but not everyone can be consistent with bitcoin accumulation. A person who invests in bitcoin from his savings over time or a person who invests in bitcoin from gifts he has received or kinda can figure out his Discretionary income at the beginning but may not be able to envisage when next he would be buying bitcoin again because he is not sure of when next he would be having a Discretionary income.
Investing in bitcoin consistently is peculiar to people who owns a stable source of income even though anyone can also have an initial bitcoin accumulation but not everyone can set a DCA approach for his bitcoin accumulation. A person who receives upkeep from his parents can also invest in bitcoin nearly consistently because he knows he would receive his upkeep regularly within some timeframe, hence we can say that his upkeeps becomes his source of income with which he can always figure out his Discretionary income to invest.
Even if you go into bitcoin investment when you do not have a stable source of income, it is very important to seek to own a stable source of income afterwards in order to maintain your bitcoin accumulation and also remain financially stress-free in order to focus and buy more bitcoin too. A person who do not have a source of income may not have a very set time when he targets to achieve a particular accumulation target, but who owns a stable source of income no matter how little can also set a goal and achieve it almost seamlessly. So it's important to understand @ejikeme's stand because I'm sure he isn't denying the ability of a jobless person to own a bitcoin, he's only doubting the ability to do it consistently as a jobless beginner.
Discretionary income is really the main point here, not just income itself.
Someone can earn $5k and still not have enough free money to invest because of high expenses, debts or family obligations. Another person can earn less but still have some little money left because his expenses are low. So I dont think income alone can tell us if someone can DCA properly or not.
But I also agree that if there is no regular income at all, doing a strict DCA becomes harder. You can still buy Bitcoin from gifts, savings, side hustle or any extra money, but it may not be consistent like someone who receives salary every month. In that case, maybe it is better to buy when free money is available instead of forcing weekly or monthly buying.
For me, the danger is when people call money “discretionary” before they have settled their basic needs. That can lead to panic selling later. DCA is good, but only when the money used can really stay in Bitcoin for long time without disturbing daily life.
