In fact although we have analyzed a project carefully, sometimes, our analysis is far away from reality. Sometimes, the project looks legit with a strong team, good roadmap, clear WP, enough funds, high hard cap, seems like a real use case, and also other promotions. but nf act they are failed. We have seen so many similar bad experiences with this kind of project. Seem like investing in a new project is like something that we may be lucky and unlucky although we have analysed it. Because we still dont know if our anaysis will realy guarantee or not.
But at least, if we ahve anlayze at elast as what @lobo13hf explained abve, this is much better than only following hype.
