Iou is a peer to peer project where they provide a good bond during a full time of the project.so thats why the have huge amount of people
Doing a full time work to the project will not guaranteed they will be going to have alot of people who are investing in the project.
But can't loss hope about the project.As the project is going very good,many people already invest here.so they are also promoting the project.all work will be paid off
Hope that will always be there, but sometimes pessimists can haunt anyone. Naturally, if everyone would worry if the project would not succeed, it would certainly be a negative value for the project.
The team is experienced enough that they already know what fault may happen & so already take measures to not get into the trap
