I think ICO started to increase day after day and people started to trust it,The future will goes to ICO, maybe because the low price or the new features which it provides.
Where did you get the static data? I haven't seen much ICO this year, and I think many people don't have trust in ICO anymore. Projects like ICOs and IEO are now experiencing a decrease in trust, so I think increasing ICOs is the wrong result. As related to the project, that when viewed static data this forum's visitors have increased. I think you need to look back at the data from icorating sites or icoreviews sites.
