I think that if this is a good project, it will not do IEO on a bad crypto exchange. From this will depend on how much money he collects. Well, maybe there is some truth in your words.
I agree, ieo is now very good at raising money and only on top exchanges, as many people have lost a lot of money due to poor-quality ico , I think it's good that this is happening and there will be less in the Scam market.
