If the team does not provide additional explanations of the situation on the project, I, as an investor, will not be able to participate in the investment, even with the promise of large bonuses.
Each participant has a personal opinion about the choice of investment projects. I think a part of the participants think the same as you. But bonuses are very attractive and can attract attention even at an early stage of development of the project.
I think that if we saw the specific characteristics of these bonuses, it would be more willing to support the project now. Of course, the fact that the bonuses are real estate makes pay attention to the ICO.
