It’s easy. Brave Browser incentivize you for viewing their ads on the browser with their platform token — Basic Attention Token (BAT). This feature is what set it apart from other browsers, because you are given the opportunity to earn by giving away your data.
To earn money through the brave browser you should do the following things:
You should install a brave browser on your device.

Then when you are done with installing, the brave browser has a publisher program which you should join and register your account.
After this, you can register your website, blog or a YouTube channel on your account.
All done now you don't have to do anything it will automatically add a payment to your account. One thing here to understand brave browser gave you money in the form of BAT token which is like for now while I am writing this answer.
How to withdraw money:
You can transfer your BAT token from brave account to you uphold account, from where further you can transfer them anywhere you want like a bank account, etc.
Have a nice day!
