Giving an image of seriousness and showing good project planning is essential to attract investors.
That is a must. Without seriousness none project will gain attention from investors. The market condition is just another aspect and it less important compared to the seriousness from the team itself.
yes thats why i'm concerned they are shifting the ico. that just looks like a cashgrab and maybe scares of investors
I wouldn't go as far as calling it that. Many projects only have one source of income - the ICO. You have to make the most of this opportunity otherwise you will run out of funding later on.
100% agree, for some projects ICO is the only opportunity to force investors to talk about them
We need to increase the credibility of the project, and for this we need to attract famous people to the team.
Famous people don't have anything to do with credibility. Credibility is all about the team and them reaching milestones on times and working on the project the best they can. Famous people are just for marketing, for awareness.
Involving famous people would probably result indirectly to higher level of credibility, but they are really better for marketing and advertising purposes.
