Well not really, anyone can gain huge in his investment with a right plan and strategy. If we know to ourselves that we are not financially stable then dont force to invest the money that is meant for important things. Just invest the money that you can live without so you wont count on this money incase emergency occur.

While its true that rich people are huge gainer because money is not a problem for them, but I believe an average investor can do it too by working hard to sustain his needs and not relying with his investment's profit.

It takes an effort to succeed so if you are lazy to work then its unlikely for you to gain huge.
