These are all nothing if it is a scammy project.
But regardless, I don't think that team should have in-depth knowledge though that would surely be beneficial for the whole project itself.
#2 is situational, though it is true but someone have their own takes of every risk.
Yes, the truth is if the project has the intentions of scamming in the first place, those factors don't matter anymore. But they can weave a good front story so people will be attracted to their seemingly "legit" project. There are some professional scammers who know how to orchestrate a "legit" project to screw naive investors. But if you see that they do have funds and not doing any type of crowdsourcing and deploying their services, then, there's hope that they are sincere with their project.
