You cannot really tell which of the tokens are the best. What I am currently doing is that I read their thread, and ask question to myself like:
Is their target goal achievable?
Is the tokens useful for end users?
Is their target niche market big or will they really earn through them?
After that if you have a good answers to this questions then most likely it is a good token, but I always look for this kind of token more so that I can minimized the risk.
for the three questions you listed, there are no projects left cause none of the current projects do real use to the end users, there is still a long way for these projects to the ground
from that question, i think we can asked by ourself because after read their project, we should asked to ourself is it good token for us? like above me said, there is still need long time to proof the token is a good one or not. for every token created, they must have a purpose why they want to create something different than the others, what they offer to end user by using the token. if you want to just make money from that tokens, then you can join with every tokens as investor and follow each of project journey and see how much profit you can make.
