It is true that the whitepaper is very useful for us to read the information we need about the ico, because in it we can find what project they offer, the roadmap and the people behind the project. But there are also some times that even if we read the whitepaper, we could not avoid being trapped in frauds and scams. So, I think it is also best to check the admins and ask more information through telegram, because if these people behind this ico is really sincere about their project, then they will get back to you and give you honest answers.
