If there is a badges system, it would be more fun to let all users able to get them. Or else it would seems a bit too much like... competitive ranking system?
For example, different badges for participation in a particular event - (es. March writer competition 2018; tipping event, Xmas collaboration etc.)
There might be badges titles for readers (es. "100 comics in the library" - Avid reader; "1000 likes" - a comic lover; "50 share" - Sharing love around)
Or badges for the contributors in tipping ("5000 coins tipped" - Generous giver, "10 000" - A wonderful human being etc).
It would makes a fun environment, badges distribution as thanks, for collections etc. They usually help to encourage more participation. Just an idea.
