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.
now ICO is not much in demand, now investors are more interested in IEO, specially launch by popular exchanges. Even the future is changing so fast and will wait for another innovation in the crypto world
You should visit the ico list site before try to say anything related to this thing. It's better to provide the accurate data rather than try to say without any data that will be supported your statement. ICO and IEO are still exist together and both were still in the demand.
