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?
I think after 2018, everything will remain the same in 2019, and promising ICO will also suffer from scammers, because at the moment there are too many of them.
If bitcoin will grow in 2019 - ico will be profitable. I think soon there will be a new boom in investing in ico
