This is a frustrating but true fact. Poverty deters people from investing in Bitcoin. They think investing in Bitcoin is too difficult and expensive. They think saving in poverty will not be responsive to them. But they don't know it, the money invested weekly or monthly in Bitcoin can one day change their life. There is no need to set aside a lot of money, setting aside a little money and saving regularly can greatly improve their quality of life. In this case I will blame their lack of knowledge.
No matter how smart you are in this case scenario of $50 per month, you may not be able to accumulate bitcoin, talk less of setting aside discretion /reserved and emergency fund because $50 is way smaller in terms of btc investment. because if for instance you are receiving $50 per month, let's say you set aside $5 weekly DCA howany Dolla will you keep for emergency and reserved and also feeding for the next 3weeks ahead after you might have invested in the first week? Surely such investment will put you in a tight corner. In as much as we talk about investing as little as $5 to $10 through DCA , we should also think of a reasonable amount that will not make us to sell off our bitcoin HODLing, than a kind of investment which is less than not investing atol. $50 is not a reasonable amount to even feed a family for 1 month so let me realistic in our analysis. Except you can invest a lum sum of $5- $10 per month which I don't know how it can be possible.
I don't know the kind of impressions you are trying to create here because every little beginning has a greater path so are you trying to tell me that because someone's income is not enough they should not make investments? a very wrong analysis sorry to say, if you can't invest when you have little there is every possibility that even if you have enough you can't still invest. You need to understand that not every one have that mindset of owning an investment even when they are rich so investment works with the ability to conquer some challenges around you and still continue because literally no man gets enough of himself as human wants are insatiable hence if someone who is earning $50 cannot make investments plan then definitely even if they increase his monthly salary to $200 or $500 he will still find it difficult to invest because he will begin to reason that now that he is earning higher is the time to enjoy himself with his family and live a better life, I have seen a lot of people do this.
I would have loved to know how much he started investing with to have made such conclution that you can't make an investment plan if you're earning $50 per month. The ability to start investing is one of the most important steps every investor has ever made and the truth is that people are of different financial class and belong to different regions and so regardless of what you are earning, if you're serious about investing for your future, it doesn't matter if you are able to start with $10 a month or $200 a month, if you're able to increase your earning along the way, you can choose to increase the allocation that goes into your investment. In a typical Christian religion setting that I'm familiar with, we all know that 10% payment for tithe is what's expected of them and regardless of wether the individual earns $50, $100 or even $500 a month, it's expected that he remits his 10% tithe at the end of the month and those that are faithful to it pays it regardless of thier financial strength or weakness.
Like you've rightly said, if you can't start investing when you have little resource, there is no guarantee that you will be able to invest when you've increased your earning. If you talk about meeting all your needs before thinking about making your investment, you already know that human wants are insatiable, when you think you've solved one, another comes right into your face. Regardless of how much you're earning, I guess it's just best to decide that a certain percentage will always go into your investment. So let's say you're earning $50 per month, you just push out $5 into Bitcoin and know that it's the days of your little begining. Along the line, you will certainly increase how much you're earning and you can easily effect the increase in the process rather than waiting till you're already made before going into making making your investment.
