Usually if they took the effort to do something about their website, their roadmap, and stuff like that, you know ones that actually made sense, then the project could be good and would be a worthwhile investment. Not that much if you're not confident, but it wouldn't hurt to put a small part really.

Of course nothing beats being an insider in their team and checking when the hell they're gonna start the pump-and-dump scheme so you can buy and sell at the right time. In the first place regardless of how they put the effort in, most of these projects are all "plans". Like seriously, they're treating crypto like Shark Tank (it's a business reality show for those unaware) where they appeal to investors lol, probably even worse since they can't even appeal a product, just a project.
