Is there a minimum milestone for IEO? so we can said an IEO is running successfully if achieve it. In my opnion, It would be great if the project team were more active here, maybe as a formality through this community.
You don't need to worry, here is a team (babenko-nickolay) who will answer your questions. You just need to be patient.
I also looked for detailed IEO information, but haven't found it yet. I only found information about token properties, I haven't found the token allocation.
