based on the data from this site it can be seen that the relevance of the ICO has decreased significantly compared to 2016-2017, people’s opinion is interesting whether anyone is following the ICO, or many have switched to IEO ?
For now many people have switched to IEO, no longer following their luck in the ICO, because the relevance of ICO has declined sharply in 2019, so now it is clear that everyone no longer thinks about ICO.
