I do not think you can find it easily but all new and old projects are promising projects but with terms and conditions.
You can say the project has a good future but the other people can not have the same opinion as you as they will use the other things to search for more info about the project.
It will be the same thing for the scam project as we do not know which project can become a scam because it will need time before we know the truth.
If there are no more clues about the project, especially they do not have good progress to running the project, that will be the time for you to suspicious and maybe you can leave it before the project scam you.
