I have a theory, if I can read cryptocurrency white papers, maybe in the long run I will be able to write a white paper, because by reading how they are initially written, their structure, technical explanations up to a point of view, and all the elements that a white paper has, I should be able to have notions to write one, what do you think?
Yes, you can. But that depends on the project you want to launch so you can make that whitepaper for your project. But if you don't create a new white paper and you copy-paste from the other project, people will know, and they will leave your project. I believe that if every people can understand how to do a project, they will have a chance to tell the details of their project so they can make a masterplan or list that they will do for their project.
I do agree, since he is planning to make a whitepaper, it should be accurate to the project he is planning to create. The idea, plan, and everything about the project. If he will just copy the contents from another whitepaper, investors/community will notice and it may be the reason for the project to get disregard by the people.
