@Prakalp first, that’s not how you earn rewards (BAT). Brave Rewards is consist of two features:
- Auto-contribute and Tipping – a feature that allow Brave users to support publisher and creators,
- and Brave Ads – a feature that allow Brave users to earn BAT; available for supported countries. FAQ: Why am I not seeing Brave Ads?
