If ANN thread lang pag babasehan mo ng legitamacy ng isang project then it's too difficult for you to recognize it. Try to visit their official site at tingnan mo if talagang legit mga team members by reverse image searching those images in google or yandex(image) like mentioned ng sa taas. Or check yung whitepaper nila if professional kakagawa or copy paste lang. Yan yung pinaka madaling pag check if legit yung project while madaming aspects dapat icheck sa mga ganyan since most ICO/ITO are scams.
