Everyone, rich or poor, can invest, if they have discretionary money or a source of discreet income. From my point of view, there may not be a person whose monthly income is less than $200. Maybe there is, but I do not know that. If you can set aside $50 discreet money monthly from this $200, then I think you are still eligible for investment. The amounts mentioned may be more or less, but I think more than $20 discreet money per month is eligible for investment. Although the amount is small, but in the long run that money can be more than the expectation of a person.
So I would say, do not give importance to the amount of income or your position for investment. Rather, give more importance to how much discreet money you can set aside. If you do not have discreet money after meeting your daily needs, then I will say with great sadness that you are not yet eligible for investment. You should look for a discreet source of income and keep the enthusiasm for investment alive. So that you can jump into investing as soon as you find a discreet source of income.
So many poor people lack patience they want it quick infact so quick that's why many of them can't sacrifice years of accumulating wealth through Bitcoin to elevate their status from poor to rich class in the future Bitcoin has given everyone the opportunity to get richer in the future but some still don't understand.
you can not blame them, some of them are just looking for fast means of making money and get misinformed that bitcoin is a get rich quick scheme which always gives them them the impression that they can just invest and get the returns as fast as possible. it is the reason why the poor rarely makes it well in their investment because most of them are always in for the short term gain.
some dont even pay attention to the need to building an emergency fund, they just invest with everything they've got hoping for quick returns that will take them from their poverty. when after waiting for bitcoin to suddenly gain momentum, it dealys, they get themselves in a position where they have to sell at loss just to survive. such people are those that end up seeing bitcoin as a scam because they in the first place came into the system with a wrong orientation.
I think many rich folks do that's why you see them buying at every given time necessary, some poor people still think Bitcoin is for the rich cause they feel they can't buy with a similar amount the rich use in accumulating, but then they can accumulate gradually as little as they can for many years and still be rich in the future.
To a large extent, a dude that knows hw is poor and can not afford to invest in the manner the rich are able to should know better and focuse on what his abillity can go for. build your income firs and then you can become strong enough to consider investing. if you are not feeding well with some left over, then investing is definately not for you because you are going to encounter a lot of discomfort as a result of little to no available resource that will aid your accumilation.
