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.
Indeed, ICO if not in this, and next year should move to a qualitatively new level of its development, as recently announced by the co-founder of ethereum Vitaliy Buterin. Therefore, we hope that in the near future ICO for investors will become less risky, and the issue of initial coins will prosper, since this activity, in spite of its shortcomings, is generally very useful.
