By default, the maximum and rate in the Brave Browser is 5 ads an hour. This video shows you how to upgrade your browser and activate up to 10 ads per hour for rewards. It looks like Brave has more sponsors and you can potentially earn more.
This is only for the Windows Browser and it not yet active for Android or iPhone.
As you can see it's quite simple.
1. Update your browser
2. Relaunch the browser
3. Go to Brave Rewards Settings
4. Go to Ads Settings
5. Change the ads frequency to 10 per hour.
That's it! Enjoy more ads and more earnings of BAT.
