There are very few ICO's that have anything worth looking at. To find these gems is exceptionally hard, because sometimes the ICO's worth looking at, that look so good, end up as complete scams, take note and point of Arcblock as an example of a scam.
The ones who revolutionize blockchains, like Universa for example, go unnoticed and have no hype whatsoever, but these types of ICO's have the greatest potential out of all coins. It isn't until they are pumped heavily, do they draw the masses attention, then they wish they got in sooner... and the cycle goes on endlessly.
The reason for this is, very few people understand what they are actually investing in, like i see it time and time again, just many clueless people. The majority of ICO's take advantage of this, and spoon feed investors and try to become instantly relate-able to that person.
A major lack of educated investments here is drawing all crypto's into a realm of stupidity, and the people who create ICO's know this, or are just creating some failed vision of theirs.
