I personally do not believe this statistics that 99% of ICOs are scam, because some ICOs fail do not mean they are all scam. I usually tell people that starting an ICO is like starting a new business, it might succeed immediately, it might fail presently but have a great future and it might fail totally beyond redemption. So because a project is failing to perform presently or fail totally do not mean it is a scam. Don't get me wrong here, I never said there are no scam projects but the rate is not as high as alleged. Judging a project based on its first few years is wrong, give it time to realize its potentials.
Yes. I agree with what you say. We have to distinguish between scams, and which ones are said to fail.
Failure is that the ICO developers do not get investors, so they have no funds to develop a new project. Whereas a scam is a project that is run that gets a lot of support and can collect more money than they expect (hardcap), but they do not run their project in accordance with the roadmap, they even run away.
