It is difficult to identify a scam project, even if the most experienced people on the cryptocurrency market have difficulty identifying a scam project.
I think if you think a project is a scam, you should not recommend it to anyone.
That's right it is really hard to identify a scam project especially when it comrs to whitepapers because there are a lot of projects that has been a good whitepaprr but at the end the project is still a scam. If we are doing a lot of research about the background of the project then we know that there are some image of it then it would be good if we will just ignored it and not support that project because it may be a scam project.
