This is not worth to believe in it now, because we do not know all the details on each of the team members, but I am sure that such information will appear in the near future.
Sometimes the project team decides to remain anonymous. Although I do not quite like such decisions, but I understand that this is their right. Maybe if I were a developer I would do the same.
What do you mean anonymous!!!! It's cheating. When you want to buy a product online, what do you do? search online for reviews or social groups that have real reviews. Go on YouTube and see what people are saying. Ie any company that deals with money should all openly and transparently show who they are. All successful ICO companies follow this path.
