I don't see the reasons for which ICO will disappear this year. ICO are new technologies and projects which will always appear. ICO of a budua to live, so far there lives crypto. ICO are things which will do our life better!
At present almost 80% of ICOs have failed, and this may be due to the effect of decreasing crypto prices.
but in this condition I cannot say that this is the end of the ICO. I am sure the ICO is still very good for investment, but we must be more careful in choosing it, so we have to add knowledge so we can choose a good ICO.
