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?
A project ICO which took a hardcap reached is a successful start of the team.
This will ensure the investors that the project will go and will be listed in an exchange.
THough this hardcap is not an assurance that the project will have a bright and successful future.
