Yup kind of as IEO are more trusted as compared to ICO view but at last it depend on project. It is also true that on average basis IEO receive more funds than regular ico and we are seeing trend shifted towards IEO.
but we cant deny that ico are also good the old times ,the only reason why ico fails is because of scam projects that uses ico just to steal money from investors. Before ,a project can reached its hard cap in just days using ico which is the most exciting when you joined on thier bounty campaign..
