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.
Though for some it might be possible, what's wrong is the mindset that it will happen right away once it gets listed.
What do you mean after the listing? Pi is already listed in many places. Are we talking about the same thing here?

Greed and stupidity is a very bad combination.
