I have been seeing reading and even downloading white paper but I don't understand how it works and it's purpose and application.
The whitepaper gives you details about their project , how are they going to success and what are the things that can make them successful. I think you just lack of analyzation to the paper. It is very important to the project because if someone wants to know more about their preferred project , they first find the whitepaper or the website of that project.
