You can head to this sub forum and browse one by one of the bounty campaigns.
You can participate in social media campaigns such as Twitter, Facebook, Instagram, and Article or even Telegram.
Still, you should be careful because not all of the bounty can succeed in the future.
After all, many of that bounty is not paying their participant.
The good news is, you can join many bounty campaigns just using your account because you only need to share or promote the project to your social media account.
That is what people did so far and yes, they earn some nice bucks there. I hope that helps you.
