I agree with @Rikafip, the trending section on CMC is based on what coins have over-performed in the last 24hours and this is coming from their ongoing metrics and not by paying the website to show it up there. Veteran users dont look into this, but rather the long term trend and development of the project.

If some random coin gets pumped to 400% in a few hours due to some pump and dump groups, it does not mean that the coin is legit, this is what a owner should know.

What you should rather focus on is developing and marketing your own project, going to niche media sites and getting articles posted there and then once your userbase is created, check the listing criteria on the support page like @Maus0728 said. Beyond that is unnecessary.
