If he has such people in cooperation, it means that the project will develop properly due to the advice of partners.
This is really very important. Therefore, I would like to see some kind of supporting documents that will confirm the fact of such cooperation. This could attract a huge number of investors and, accordingly, investments in this project.
I think, that some information on this can be read in white paper. however, there are no special documents for this. however, we want to see at least a photo
As I consider, the team photos are not such an important aspect in the development of the company, as the development and the idea of the project.
