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.
Really hard to tell which project is really be having those kind of motives and dedication on developing out those things that they had promised or stated into
their whitepaper or following their roadmap or simply trying to make those promises come true on where they had stated when they are still on sale.
Lots of sweet words and promises we can really hear off most of the time specially when the project is really just starting up.Everything seems legit
and real until when the time comes that those devs will just simply ran off all of those funds when they had accumulated enough.
This is why we do need in depth research.
