Some things need to be considered when it comes to investment comparison between the poor and the rich. That mindset would definitely be hard for the poor people to overcome since it's evident they struggle for money to feed. Rich people can easily make that decision because even if it later backfire, they probably have a back up and would be less affected by the consequences. The phrase "we use money to make more money" is very underrated but it's actually a reality which is the reason the rich people are getting more richer while the poor are becoming more poorer.
This isn't a fair comparison because you can never think about investing when you don't have a steady source of income because all they're thinking about is how to make money for Food and other family expenses. There's nothing wrong with this mindset, as we'll experience it in that situation. The rich have the resources to multiply their money through investments, while the poor are only concerned with survival strategies in unstable financial situations. That's why I say that the poor's mindset makes it difficult to make investment decisions because it requires balance before making money.
I have reasons to disagree with you idea about investing in Bitcoin mate, particularly the part you said one needs a steady source of income in order to invest in Bitcoin and the part you indirectly insinuated that the poor is more concerned about survival and so can't easily invest in Bitcoin.
first of all, it really doesn't matter whether you income source is steady or not, as long as you're able to discover your discretionary income, you can invest in Bitcoin, whether your income comes once in two weeks, monthly. your accumulation could only go on a faster pace when your income source is steady, maybe weekly or so cos it gives you more chance to buy Bitcoin, but that doesn't mean that those who are not on a steady income cannot invest in bitcoin.
secondly, whether poor or rich, anyone can invest in bitcoin, as long as they've got the right financial management, being poor doesn't mean you won't have discretionary income from your earnings, regardless of how small, they can still gradually accumulate bitcoin overtime and since Bitcoin is a long term investment, they'll definitely have all the time to accumulate bitcoin and reach their fianancial goal.
