I think that in 2019 ICO will be still alive, ICO investors will be smarter and only join good ICO. No more lands for bad and scam ICO. 2018 is not a good year for investors because most of token dumped below ICO price. Do you think 2019 is a good year for ICO and all tokens pump after ICO like it was in 2017?
ICO's will come back when the market comes back. Notice everything dealing with crypto is in the gutter. Airdrops suck, bounties suck and mining sucks. About the only place that doesn't suck right now is trading (assuming you have skills). Everything else is dead right now.
