ICO is not a guarantee that the project will be successful, because most ICO projects are still limited to concepts and do not have clear references,
but projects that don't make ICO or premine are usually serious and good projects.
and I also agree on this, what about your opinion?
even if an ico only makes it to the soft cap, it can prosper as soon as the project is sound and they have a dedicative team that works hard every single day to make things happen. Hitting the hardcap might got some of the disadvantages as well like the project is so hyped.
