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.
I also believe that there are still legit ICOs who were not able to develop their project due to lack of fund. I've had some bounties from ICO and were part of their telegram group and I can see their team doing their best to update and develop their project slowly. The problem is investors, not all of course, are impatient enough to give chance to support the project.
It is just sad that this projects who are striving to provide legitimate product and services fet affected due to the numbers of scam ICOs that are popping which results to investors losing faith to other ICOs.
