ICO will continue to appear with new tech and even new innovations that will continue to vary. expected by the existence of this will keep popping up in the increasingly good cryptosystem and could be a new crypto can be the best. Although currently looks a lot ICO falls but that does not mean it will stop until here anyway.
As for the fact that there will be a lot of new ideas and technologies used in the blockchain, I agree.. There are still many projects ahead. 2017 was just a boom. 2018 is a consequence of this madness that took place in 2017. Then everything will be tightened and the ICO will be like you said better.. I think that verification and bans will allow you to get more in the company of a bounty hunter.
