First time trying this kind of thing.

I hope I get it right. 

So, I applied for a crowdfunding program and finished the tutorial. I hope everything worked and make me more motivated to write more. For now, I can only offer a 1$ monthly-subscription. Initially, I write fanfic just because it is my hobby and I don't want to charge a lot for that. If I want to charge more, I think I need to offer something that can satisfy people who read my works. But what kind of service I can offer then?
