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?
I've seen a lot of projects that reached hardcap, and yet some of them until now they never distribute the token rewards to their bounty participants. Ans sometimes there are ico's only reached softcap but in the end they've become more successful rather than the project who reached hardcap.
