Any live interviews from the team I think that will be a good plan to attract members and investors to join the ICO sale.
Interviews are an effective step to attract new users, but this step must be supported by a great team that can convince the audience. don't forget promotions through social media, because almost all humans use social media and that is the first step in platform imaging.
you really have the right views about the interest in this project. maybe it's the first thing to pay attention to. Indeed, indeed, social networks are now very popular and many people use it and learn a lot of information from there.
If they are give a live interview that would be an effective solution to gain trust from different investors since they are being transparent to the audience they have in this project.
