All good points... but to be fair, unrelated to the "being or not a shit coin" (in my view and considering your arguments for decision making). Some of top 50 coins (market cap) never had white papers, websites, nor any kind of social media sharing, when they have been announced and nevertheless people had believed in them (some not)... and now they are at the top.
I am not saying it is or not a good investment because I understand how hard is to decide on +500 new stuff every year... all I am saying is that it all depends!
Always do your own research... but I would also say, never stay sceptic to something just because it doesn't look that good. Be positive instead and try to find new information in it, that sometimes can work well to your advantage and help the community. I know there are lot's of scams and people trying to fake identities, but there are also lot's of people that are around these things just to win their buck, and those people sometimes will do whatever necessary to make things appear a certain way. Although... they might not...
Sometimes apparencies, elude!
Wise words, my friend. I could not have said it better myself.
