I know some people in our country who’ve already been scammed by Ponzi schemes, yet they still join again and just treat it like they’re gambling.
Just like people who lose funds in a collapsed centralized exchange and still leave some of their funds in another centralized exchange, because that one hasn't collapsed yet, it is crazy to think, but a lot of people do this.
There would always be people who would still make the wrong decision despite numerous warnings they have heard. Not your keys, not your coins, they still store funds in centralized exchanges, anything that is too good to be true is probably a scam, they still join ponzi schemes, etc.
That’s valid too - but at least with exchanges, they’re not outright scams.
Unlike Ponzi schemes, where the ending is already obvious, and yet people still choose to invest knowing it’s doomed.
It’s different when we compare that to centralized exchanges. Yes, we leave our funds there, but the chances of the exchange getting hacked are much lower compared to the guaranteed 100% failure rate of a Ponzi scheme.
