Development Bounty is to reward developers and coders for contributing to the project (project owners can decide and specify other tasks and requirements too) in finding bugs and testing products. The budget is higher for the obvious reason and that is the development is a very high profile activity and it is not as easy as doing normal tasks like making tweets and sharing posts in social media platforms. That's why the developer bounty has to be higher.

The developer's bounty is not a new thing. Bug bounty is also a kind of developer bounty which is very famous in the mainstream industry. Google, Facebook, Paypal, and so many other projects has been doing bug bounty and paid millions of dollars till date .
