There are 2 places where legitimate projects show up before they pop off that you can keep an eye on..

- VC desks (and websites under their portfolio)
- Crypto job sites (and linkedin crypto jobs)

These are usually more legit projects as VCs have done their due diligence on them, and a lot of the crypto jobs websites cost like $300 - $400 to post a job, which I feel a lot of scams or low effort projects wouldn't bother with, whereas legit projects who are building out their team would..
