I think there must be some criteria that can attract the investors to join in your project.
1. Give the new and unique concept of the project, not similar as the others.
2. Put your ream team members in sure, yeah I mean that the trust is very important
3. Make good promotion method, such as using bounty programs, making certain video, advertising in google, promoting in social media actively, active in telegram community
4. Go abroad and offline to introduce your project into the market in real world.
