cheated? a sure thing if you have been exposed to fraud then you have to further improve the situation in the future. to prevent this from happening again.
But do not forget that fraudsters are also improving in order to deceive you. I agree with the author of the post that first of all it is better to learn the team and the despicability of the people who are behind the project.
Just be very diligent with your findings, that is all. The thing like you said is that fraudsters keep looking for new ways to keep upgrading with their deception, so in a way, the best thing is to make sure you are always a step ahead in most cases, and how can you do that? Just make sure you are basically not just looking at the surface, but checking out all the necessary things you need to know and as an investor, never be lazy to keep asking questions until you are fully convinced.
