a simple example like the unidapp project. Currently, the project is under suspicion of being a scam project because it does not have complete information, and complete information is usually found in the whitepaper, whether it's the concept or team identity, all in the whitepaper. however, the whitepaper is very important for a project.
This will be a basis of the tech and platform use case. So if a project doesnt have this, means they are not sincere to launch a good project. Whitepaper show the true power and strenght of the platform. It will be a guided technical written report describing all aspect on what to expect on a project. Whitepaper is vital so better to have a good perception on it.
