One of the ways to verify if a project is fake is to check if the whitepaper is plagiarized or poorly written. According to what I've seen, since the intention of any fake project is to steal investors' funds. Most times, these scammers don't like spending extra money writing a well-detailed white paper about the project. They either end up plagiarizing other projects or write a whitepaper with no correlation between what's written in it and the project and If you can spot any of these, that's a red flag.
