From a crypto-trading perspective, there's nothing wrong with being involved in PI. However, before the listing, there are lots of PI delusional thinking that it will be worth $100 right away at the listing, and even comparing it to how bitcoin was progressing.

Too much expectation that the PI will give them a life-changing moment.

Though for some it might be possible, what's wrong is the mindset that it will happen right away once it gets listed.
