Unfortunately we usually can't know until it's too late (or it's a bad scam ^^). Some dishonest people are very clever at making others believe anything.
Personally I'm suspicious when it sounds too good to be true (it's true in all domains of life).
Even with a super team and a super whitepaper, nothing is ever sure (I would rather look at big partners who could give credibility to the project)
Yes, scammers will never say they will scam you. Every plot has been planned so ahead, they are a group of scammers and they are smarter than anyone.
Strategic dashboards can also be an organization or agency drawn up without any agreement with them, most probably with projects supported by other major platforms such as NEO, ADA, ETH ...
