Girls in promo are really hot. I am sure they will have fans.
But will be it enough for project's success?

Seriously speaking, it's the matter of how many fans and what kind of fans we have. As to the token sale success, we need the community of not only fans, but also investors. Besides, I'm convinced the project's success doesn't depend on how successfully the token sale has gone. The token sale is only the tool, not the goal in itself.
