But how can we find out whether this team is fake or not. They can make fake team profile, i can not know about it. Is there any clear way to find out?
Yeah, you're correct,to an extent it's almost impossible to be 100% certain a team/ico is a scam, but it's very possible to make an attempt and be correct.
If you study @OP'S guidelines thoroughly it'll aid you to spot a SCam ICo, so you can stay away from'em to avoid losing your money..
One way to know a fake team is through a project that doesn't look feasible,just laden with promises and high expectations that you damn well know for sure that a new coin wouldn't be able to achieve this..
