You can ask every scam questions for understanding about project. What do you need to know: white paper, card and soft cap, actual topic of project, for what money, how they built promotion, what the team, what the token.
Indeed. Asking and clearing of questions and doubt is always necessary to ensure that you have invested in the right ICO project. One must ask questions to the team on twitter or telegram group about their development, their vision, their soft cap and whether they are arranging bounty campaigns or other activities for promotion. Also keep yourself updated about the project by asking questions about their work and progress.
Do you check the information also from another source than the team? It is of course very likely that the information from the team will be biased.
