Why in the world people buy into influencer coins?

This happens all the time, like a perpetual motion machine. Rugpulls are so common that one Google search will be your saviour. But they still manage to get millions from people.

So how come that people spend their lifesavings buying into some weird things that cpmes from a shady celebrity whose whole career is based of a stupid joke etc?

Don't they have some kind of self-defence reflex that says "nah, maybe putting 40k$ in a shady coin of a weiner spitter girl isn't a good idea"

I was thinking it might be some gambling addiction thing, or maybe even misjudgement of some sort? Because i still can not believe that anyone can trust their life saving to a NOBODY from internet. To someone who has no obligation to make you profit or even save your money. What do you guys think?
