Question about successful ICO startups

[ValeryKim_849Y]

Hello Guys,

I was watching successful ICO startups and some of them got huge funds on crowdsale. And I got a reasonale question, I think experienced guys here may have an answer:
After successful crowdsale if you have some funds that exceed the required amount of money for releasing and supporting a product which way do you think is the best to spend(realize) that amount effectively in "product's interest"?

Also I'll be very appreciated if you will post some interesting ideas or points of view on this question!
