Well, honestly, I have not read much about whitepaper. I only check whether the projects are scam or not and I only spend a couple of minute to analyze the plot of whitepaper. And in some projects, I never read their whitepaper. Maybe its because they are too good or they are 100% scammers. However, I still recommend people to read the whitepaper. Why? Because it contains a lot of information about the ICOs that you might put your money in. By reading the white paper, you will understand more about the project and you will know what their products are and how they can help the world with the funds they have
