You can always chose patreon If you wanna earn money from writing fanfic as if not then well you can earn by writing original. Well whatever good luck for the career you chose and be successful in that path.
Nah. I know myself that it will just be more stressful to do that. Besides, with no mobile phone to use on a daily basis, it will be hard to maintain. đ I'm not the modern kinda guy who's always online so earning money like that isn't my thing. Also, there's only a few people, or none at all, who'd pay for chapters.
