I sincerely agree with your narrative, investment are mostly done within the capacity and means of an individual, you don't need to have huge capital before you think of investment, a little drop of water they say makes the mighty ocean and considering the fact that is a long time investment, it is most appropriate you don't go beyond your means because it should be discretionary within your limit, maybe with time hence there is increase in capital you can as well increase your investment.
It is important that the investment is long and continuous, not large. This means that if you do not have a large capital to hire a bin, there is no problem, you can invest in small amounts by DCA. But you must maintain continuity and be committed to keeping the investment for a long time. On the other hand, if you have a large capital, but you cannot be long-term in investment and cannot maintain continuity, then the end result of your investment is completely unknown or incomplete. You may not get big profits from such an investment or you may face losses. I always remember one thing, "Even if the speed of the car is slow, it is possible to reach the destination, but if the car is unable to move continuously, it is impossible to reach the destination or it is difficult to reach the destination in that car"
So even if you do not have a large capital, you can reach your investment target, for this you have to maintain long-term planning and continuity.
