The only question is, is there any project who did that? There might be some in the past though I can't say the projects because I forgot them.
I've seen projects in the past that offers a completely new technology, and it seems sustainable in the long run, but for whatever reason it is, it ends up as a failed project. Nowadays, a completely new concept is very rare already, and most of the new projects that are popping out of nowhere are just either a clone of an old project, or a project that integrates 2 use cases from 2 different old projects. I don't want to say that it's bad to copy, but that strategy will not be sustainable in the long run, and that's the reason why most of the projects are failing I think.
Anyway, to answer your question on how to tell a new coin if it's worth investing in, there's no way to know it since you don't know the future of every new project. What's certain is that most of the new projects are ending up as a scam whatever the concept is, so in short it's hard to know.
Whether or not a project is worth investing in, apart from innovation and the need to verify that the technology can achieve its goals and is not just an empty dream!
Your username speaks on the project that you want to advertise here. I guess good luck with your new project. Hoping that your project will be a successful one, your project will be different from what we are seeing already, and you will not scam investors.
Thanks, I won't promote this project blindly because that doesn't make sense, the only thing to look forward to is to really understand the market demand and complete the new idea, only if you take it seriously, then you can succeed.
