It is enough to look at their website to understand that it is not a GEM. Good projects don't skimp on their UX/UI. Learn to distinguish at least at this stage.
The second thing I can see is a lack of investors (at least 3-4 Tire)
We have similarities in judging projects from website appearance lol, because every gem project has an elegant website appearance according to the theme of the project but low quality projects usually have poor and unstructured appearance of every component displayed on the website.
