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.
No one is saying all ICOs are scam but from the information gathered on ICO projects, a greater number of them appears to be a scam. Developing a shitcoin is scam. So its not about being quick to judge rather, a way to help people from being scammed...
A large number of scams happen not because of scammers but those people who are fool enough to think that there are easy ways to make money. It is not possible that you get gigantic benefits by putting negligible effort. Also, would not it be much better to just stay with the coins that have already proved to be the trustworthy ones instead of trying upcoming and new ICOs daily?
