Perosnally, I haven’t written anything on wattpad before, so I don’t know the income, but from what i found it depends on the number of people who watched the ad.
Wattpad’s writers’ main source of income depends on ad revenue, just like youtube and webtoon.
I have no idea and never heard of anyone earning money from Wattpad, but I don’t think you can make enough as a regular writer to make it your main job
A friend told me a few days ago that you can earn money from ads or just views when you’ve published on Wattpad for a year. I don’t know how much that’ll help with earning money on Wattpad but maybe someone of the @WattpadWizards knows more about this?
What - anyone? Or just the popular authors/writers?
Apparently it’s for everyone but I haven’t checked yet, just heard it from a friend
Oh, really? How long has this been going?
I don’t know exactly but I found a few infos here and here
Looks like it’s not really one year of being there but some kind of program that gets you easier access to make your story a paid one 
I wonder how much money that can earn you
