How can we safe ourselves from well organized scam projects? Some projects are so well crafted and in the end they scam people, to my own understand research doesn't help here at all, use case, whitepaper, team, every thing are so real and make sense, please give advice about this
Extensive research. Not just the kind of research wherein you're just scanning the project/startup's website and not doing extensive background search.
You need to look past the wonderful looking website, the listing promises to a prominent cryptocurrency exchange and even to how well-known the team behind such a project is.
Dig deeper until you find some red-flags. Avoid getting lured in with the "nice things" others may say about the project/company; you'll have to do your assessments on your own.
If everything checks out then you may jump-in, but remember, invest only what you can afford to lose.
These stuff mainly the critical points participants are missing out. Scam projects aren't that dumb to let themselves be find out easily. So as persuasive the project may look like, hiding shading things would be on their top priority but that doesn't mean they'll get everything cornered out. If you are going to dig deeper you could find those unusual things and be soon can conclude that such project ain't real at all. So, yes, research is still a thing though but do it not in general way. You know, small pebble in your shoe can ruin the whole marathon.
