BGL PR bounty hunt ($10000 overall budget)

To get more people involved and provide motivation, we are announcing Bitgesell Pull Request bounty hunt!

The rules are simple:

- You can create any reasonable pull request that may contain any modifications, including, but not limited to:
- Refactoring and simplification;
- Test fixes (1 test group/file fixed by single PR counts!);
- Cleanup of features that are no longer used (e.g. non-segwit transactions);
- Documentation and comments (but if no code changes then some reasonable amount of changes should be done to count);
- Bug fixes;
- Every PR would be paid $500 in USDT upon approval, larger PRs could receive bigger payouts (PRs of lesser significance like comments editing or one-line changes could receive lesser payout).
- Interested people are welcome to become maintainers of the project;

The issue names no files, tests, or entry points and does not define a specific change. First review the repository to identify a narrowly scoped refactor, test fix, cleanup, documentation update, or bug fix; done would require a pull request that maintainers approve under the bounty rules.
