Number 3....do you know why? Because I want to maximize every potential through the research I or others conduct with my full power. Moreover, thinking before acting at least prevents us from relying too much on luck, like gambling. So, investment is an investment, and it really bears the fruit of thoughtful consideration, even though the outcome might fail or succeed.

I'm a bit skeptical about number 2... is it really a Ponzi scheme, which is considered bad by many people? I'm pretty sure that's not the type of true investor worth acknowledging.

As for option number four, I believe only a few people would choose this to boast about being "rich." This option is full of arrogance in its explanation as well, so anyone who chooses this option should be able to prove that their wealth is valid. Even true wealthy individuals seem not to consider themselves rich and knowledgeable because there is always another sky above and more stars.
