There are alot of Bounty campaigns out there, and there are a number of diffrent ways to join them. If you got alot of followers on Twitter or Facebook you get crypto for sharing their tweets/posts. Same if you got a big blog with alot of readers.
If you know any other language other than english you can also translate their website/whitepaper in exhange for tokens. You should visit the Bounty section and start participating! Its fun aswell.
