Sometimes five years ago, trading fees are not at all a concern. But nowadays people are considering high transaction fees is an obstacle for success of coin. But, definitely I will not agree with that because bitcoin is right now having massive transaction fees still it keeps appreciating. On the other hand market capitalization is just another metric but economically not having any significant meaning.
A real use case and active devs team are more important in my opinion. But nowadays, coins with the no real purposes are finding success because of heavy promotion. When dev team is coming up the strong marketing strategies then they are easily hitting bull's eye.
I definitely agree with you mate, for me first thing that might be the major reason for a success of a certain project or ICO goes to the active and development team behind every successful token. There is no other than to credit but them because they are the reason for a successful improvement of token that leads to atteact investors or traders and mass adoption.
Lets just take a look with the high gas fee of ethereum too, this is the main concern for every traders and investors for the last couple months but it has nothing to do with the successful market of ethereum today.
