The sad truth here is that only few good projects can fund their own, mostly ICOs are depending on the investors because most of them really just focus on the profit they can earn in that project.
Why they dont fund the project up to its success?
-easy because even them dont trust their own work and they also have a doubt that the project sometimes cant succeed even its good.
Unlike before way back 2017 I think, ICOs are few thats why investors can earn.
