Crypto is far from being killed so don't think that we're going to that point. The idea of crowdfunding came early and those successful projects were funded appropriately. But failure is already there and not every project that held ICO/crowdfunding became successful.
Is your main idea to support the project or just to make profit from the bonuses and go your way?
I don't join any ICO but if there will be an interesting, I'll support but you can't deny the fact of having some profit.
