P2E is the new hype that is starting out.

My suggestion would be to go with the beta project first, pitch it to private investors - that is angel investors first. Using that capital start your team and get the marketing out there and announce a public offering.

You might not be getting millions but you should get enough to start off. In a way the private investors will have their own lock in period at which point they will sell off their stakes and after that the project has to run with some sort of inherent demand creation - possibly an in game currency which most users hate. But it is like that if you cant think of anything better.
