Keep in mind that well over 80% of all ICO's are scams (that estimate would still be very optimistic, the real number might be high as 95 or even 99%)!! Of course there is some promising ICO's as well but because 80-99% of them are scams people are starting to be very afraid and careful to invest in any ICO's (including the most promising ones), and this will hurt not only the succesful ICO's but also the whole Ethereum community.
That 80% is a number that gets quoted often but if you look at the original source they count every single ICO that failed to reach its soft cap and returned investors money as a scam and every ICO project that never got to the point of raising any money. The fact you include 99% as a scam shows you have not a clue what you are talking about. I have done bounties for over 200 ICO's in the last year and only 20 have turned scam as far as I am concerned and I include those that reduced their bounty in that number. As far as outright scams where they ran away with the money I have only had 1 do that.
