certainly the project was too greedy and they were not confident. if they believe the project can be successful, they will only use one of them. doing IEO and ICO together obviously makes investors confused. if they want to do both, they should do it separately. IEO or ICO first, this makes the project organized.
I don’t think there is any project that would be that greedy to run both at the same time, it is absolutely impossible and any project that does that is certainly a scam project, because of the ico market that has been damaged, many developers do not meet up with their target again, which I would call softcap and hardcap, so what they do is to either start with ico, which if they find out that the ico is not moving, they pause it to continue on IEO in that case of harmony.
Another project that we could see run ICO twice are some project that start from phase 1 fund raising first, and then use it for development to some extent which they come back for the second round for the completed part of the project, so I therefore disagree that both of them would be used same time by a developer who is not s scammer.
