I suppose that ICOs in 2018 will move to a new level. The amount of project will be reduced, but the quality should be improved for sure. Moreover I guess that in 2018 ETH will share the place of the top ICO platform with NEM, NEO and other projects.
yeah, I hope that the quality should improve because most of the ico's today are scamming their participants of campaign and because of that more and more people are getting tired of promoting those icos.
