This is the first thing you should be looking at in a project before deciding to invest or not because if you invest into a project that has no transparency, you'll be left in the dark always and there's a high possiblity of the project turning into a scam as investors won't know the moves the developers of the project are taking to protect their investment by selling or keep holding.
Scam project always hide things or use fake credentials as they know if the community gets to know about what they hiding, they'll be exposed and their trick to scam more users will fail. If you noticed a project isn't been transparent you should sell your investment immediately and exit the project as this type of project always end in one way and that's exit scams.
When a project keep promising their investors unrealistic promises it means they have no product to show and only depending on their promises to retain their own investors. Also when a project only talks about the possibility of them having a particular price target in few years, you should sell all your investment because that project is full of bullshit and a scam token.
