Are you asking what their aim is? Profit. Short and simple. Not everyone has morals or they have such backgrounds and live in places where they don't afford to have morals.

When you are investing into something new, always assume that at some point they are most likely going to do an exit scam. You'll be safer that way.
Good projects will have real doxxed devs with a proven history of building stuff. If you are investing into anon dev tokens, changes are that you are only going to get scammed. It has been so since from the start.
