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?
ICO is just a way to find funds from investors, so in my opinion ICO does not guarantee the project is successful or not.
The success or failure of the project is seen from developments that are up to date and also transparent and do not exceed the specified time limit.
