Thanks for the answer! After reading one of the comments that said 400$ (per year) is the maximum for beginners, i become frustrated. So i want to believe this is not true. Even if I can make 200$ from it per month, this is already a huge success for me.
that depends on what kind of project you have participated. That's why you must DYOR to get a legit project.
I just give you an example if a blog bounty participant on the hex bounty campaign that has ended a few months ago got $600 for one article.

As long as you can make quality content and you will get the reward and pass the qualification from the manager.
