One of the signs I expected you to mention is plagiarized white paper. Most fake projects have lazy people that just plagiarized white paper.
2. Unrealistic promises: If a project promises too-good-to-be-true returns on investment, it is likely a scam. While some crypto projects are innovative and have the potential for significant growth, investors should be wary of promises that seem too exaggerated.
I do not know about this, but if a project presell a token at $1 and said to list it at $5, that may look not realistic. They may also said that the coin mat do 5x more which might happen or might not happen. What unrealistic promise are you talking about?
1. Lack of transparency: A legitimate crypto project should have clear information about its team
Oh no, there's no transparency behind Bitcoin's team, we're only know the name of the creator is Satoshi, but it's still not known about it's she, he, them, race, religion, face etc. So yeah, we can call Bitcoin is scam and anyone should sell all their Bitcoin ASAP! /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.
This approach from the project team looks strange. The announced price for pre-sales and at the time the token goes public is almost unrealistic. This requires super promotion of the project at the initial stage. This is not visible. Definitely smacks of scammers
