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.
I hope this will be the case and not totally dying off. I mean, as bad as ICOs are imaged and known to many bitcoin users and traders, like it being a scam or a scheme used by some people to take advantage of other or steal useful data, I still think that there is still good in it because many starters and newbies use it as a means to earn token and coins. Not everyone, especially those who are just starting can support or have the capital to trade or invest without having a jump start to even have an asset to invest or trade, and that's where ICOs come in.
