I don't think there truly is a way to tell until it's over and it becomes obvious to all.

Smart scammers realize they have to go to great lengths to fool people and so some are.  The amount of money some of them steal is incredible, so it's no surprise there are many scammers out there.

Yes, it sucks to work hard or invest, follow and support a project just to watch it evaporate into thin air.  But such is the nature of the game at this point in time.

What is shows diligent crypto-enthusiasts is the only way to get ahead is to cast a wide net and trust your gut feelings as much as necessary.  I've been victimized by scams like everyone else on BTT.  Until you have been scammed, you can't really comment on the scene but must make judgments based on other's experiences.  Plus, until you've been scammed, you really have no idea what it is you are into until it happens.

Research, active involvement with projects, conversations with team members, and your gut feelings will take you a lot farther than you realize.

Folks are so used to a government edifice 'protecting' us from bad guys with regulation, that the crypto Universe becomes a true wild, wild west that most do not have the wherewithal to navigate successfully.  My number one piece of advise:  Listen to your guts!  They know more than you think.
