I think yes , Trend will get down much because here present time even not profitable for the ICO launcher team , We can see everything month 3,4 ICO project are launching but we can see that crowdfunding/investment are not going so high as it was about one year back , and also this results into down stable market of the etherium coin .
So most probable chances are that ICOs project will no more be profitable in incoming time and people will understand very well that they should not launch ICO project blindly and in that way only limited numbers of ICOs will launch by them .
