Currently the Trending Collections section is limited to only displaying the top 5. My suggestion is to add a "View All" button that would show an expanded view of rankings with all collections. This expanded view should also include additional stats like: Floor Price, Volume, % Volume Change, Number of Sales, Unique Owners, Total Supply, % of Supply Listed. I also suggest that Floor Price and Volume be added to the basic view (before a user expands with "view all").
