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.
yes a new idea indeed needs to be done to improve the quality of ICO. even my prediction, ICO in 2018 will increase in number. remember because many companies want to get a lot of results. but there should be an agency that filters out the ICO's right to slide or not so that the scammers will not be able to move again and we will not get stuck.
