the reality is very true, that until now very few projects have run sales with ICO. however, I do not think that this will completely disappear. When the cryptocurrency price recovered, I thought the developers out there would re-develop new projects and make sales through ICO. although a little, I'm sure there will still be.

Besides that, although IEO also has advantages over ICO, it's just that, I feel that there will be developers who see how many investors are interested in their projects and do ICO in the future.
