it is very difficult to determine the current scam project because all of them have almost perfect whitepaper websites like real projects and for that I often see teams and also see
https://bitcointalk.org/index.php?board=83.0 because there are always updates to project discussions scam there
no one can know that this scam project at the beginning of the project I think is a very difficult thing to do because we know it at the end of the project in conditions like this we as investors must be smart in choosing good and profitable projects
