The true answer here is nobody knows for certain, and it's always best to "do your own research"... or "DYOR"
When I am trying to determine if I will be investing in a new coin I try to learn as much about it as possible. I start with this list of the top 100 or so coins (keeps growing) that have very simple explanations. If I am interested in the problem they are solving, I dive deeper into the coin.
Its great too because you can search by category. Lately, I have been most interested in social and platform tokens.
