Early detection is way possible unless the team was so bulgar from their plan. Because I will tell you that these scammers are too smart as well and they perfectly hide their real intention until such time they've got money from innocent investors. That is why investing new projects are too risky and a possible chance of getting fallen into a scam project which is why it was encouraged to just invest only in those projects that already have a market record and shows potentiality as we can at least assure something about ROI.
