I didn't see any information about refund to investors. For a loong time i do not following the information about this project since the team of Athero's gone and not active on the telegram group.
This is their previous post that said if investor funds have been returned
https://bitcointalk.org/index.php?topic=5036025.msg52035370#msg52035370 but here there are still many who do not believe about it, and are still tracking the refund
so, this project failed ?
i think, the team member from this project should come here and give a clear explanations if they already refunded all money to their investors
such as proof or something else
