I would also add that the important point is the active life of the project. I had the opportunity to compare projects and those that showed their activity
and those who openly positioned themselves come to success. The last my such project Vreo.io https://bitcointalk.org/index.php?topic=2886707. The team travels throughout Europe and even America, present their project at various cryptoconferences, were interviewed for television and blogers, magazines write about them articles. Such an active position inspires confidence
