One of the signs I expected you to mention is plagiarized white paper. Most fake projects have lazy people that just plagiarized white paper.
/jk.
You are getting it wrong. Let me give you an example. Assuming the people behind the project said they will list the coin on an exchange, but should make your findings to know if that is true. If you later make research and the exchange said it is a lie, know that it is a fake project.
Also know that some projects may want to be a good one, but later in one way or the other, it becomes bump and dump or become failed.
If you want to invest, I will advice you to invest in bitcoin.
Very surprising you reply my post in serious, when I already wrote
/jk as the sarcasm sign.
A project can hire a high skilled writer to write their white paper, now the scam project is already looks legit.
The team that sad they will list the coin on an exchange are only give promise, when the deadline come and they not yet list their coin, they will give a clarification and say they will try their best bla bla bla.
There's no sign to know the project is scam until the time come.
