I invest in new projects, but very selectively. And a new project for me does not mean that it only appeared on the Internet yesterday. I prefer projects that are at the very beginning of their development but have already shown some results. The project needs to be highlighted by its team and be in touch with its community. Strictly follow the terms of your roadmap, and not be a "pig in a poke".
That's a good standards of yours as you choose to invest in the new projects. It doesn't really mean as they're new but they have a clear vision and mission of their project.
It's what everyone has to do if they're interested in investing into the newer projects. There are interesting projects that shouldn't be ignored but, there are more of those projects that everyone has to ignore.
