I agree to this but its not definitely all ICOs are scam. There are still good ICO projects that are not scam but just didn't collect the enough funds to make it continue so it stop and return the funds to investors. But the point is that 4 out of 5 are scams.
So you are looking for a bounty like finding a needle in a high haystack and finding it hard. this is how this year is going to be for not so much for all projects.
