Hidden team members in any project, this is the question mark on project ? is this project really legit?
Well real projects never hide anything related project like team members background, their experience these things can attract investor to project.
If team already hide from project then this kind of projects never last long in crypto field and fall becomes project destiny.
Having hidden team members would result in doubt of the one who sees the project that can result in the distrust of the whole community. We do know that good projects didn't hide their team identity at the start of their projects that made the idealism of having a project that hides the team member's identity will have a high chance of making unethical business scenarios such as scamming and also make the community suspicious of the project. Revealing the projects team identity isn't a requirement but it is the standard to make the project successful.
Doubt and uncertainty are the mental state that the investors will feel because they do not have any idea on who are the people that are running the project. If I'm an investor I will probably ignore those projects who doesn't naming those people who are behind those projects. For me, the scam probability will easily increase because the name of those behind the project are unknown and you cannot sue them if it is really a scam. Trust is important in a project and team members should give a short background and information about all of them even though it is just a piece of sentence as long as it is well detailed. I really do not suggest to make investment with hidden team members because the risks are too high where the possibility of you losing the money is also very high. Avoid project that have hidden member and just focus on projects that have information about the team behind it.
