if you are trying to say that poor people can't invest yes if they don't have computer, but being poor but they have money they can rent a computer for example, since internet on some places are accessible and they can rent for a few hours, then if they have save a bit of a cash they can do so, its just a matter of how or need to find a way to, you just need money some people are poor but in reality they are just saving, so i think if they can learn or know about it they can invest with the right people teaching them, not with those who will take advantage of them.
I will take the computer writing to be capital, and your financial status should not be a challenge. The challenge is the capital, and one thing the person needs is a source of income, because that way, they will be able to do DCA, which does not really have anything to do with their financial status, because there are a lot of things that, if they are properly put in place, they don't need to worry about your financial status; you just have to have a specific amount budgeted for your DCA.
And if it is about saving your money, is it not better to just use the money to buy Bitcoin, because it is not as funny as we all think, but these things can be properly put in place because the information for guidance is already there. so how you make use of it is what matters because that is what is most important.
