Naturally, before investing it is necessary to study as much material as possible about the project and reading White Paper is one of the important points. Although I can say that I invested in two projects without reading their White Paper, but they were both successful enough. I met projects with a well-written White Paper, a good idea, but they did not succeed. I think that to select a project for investment, you need to look at a lot of things, for example on mentioning in the press, to study each member of the team, to look at their social pages, if possible, to communicate with them. Openness of the team is the first sign of trusting the project.
