most of the fake projects are usually poorly executed. Which means their website, whitepaper and idea are all made in a rush, which is usually the case. Another good indicator that a project has an idea that is "too good to be true", I've recently seen a start up that wants to focus on flying taxis (like flying cars). I mean, I'm all down to fly and go from one place to another real fast, but the goal has to be somewhat attainable, if flying cars have not been fully developed yet, then it's unlikely that a coin start up will all of the sudden find the solution and create the infrastructure necessary to attain that. The goal has to be both realistic and tangible, the consumers have to be able to adopt and developers should be able to build on something realistically.
