BGL PR bounty hunt

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 **$100** in USDT upon approval, larger PRs could receive bigger payouts.
- Interested people are welcome to become maintainers of the project;

(multi-contributor bounty would be recreated when possible on Gitcoin soon)

(I miscreated issue on personal repo, please make PRs and fork them from the repo github.com/bitgesellofficial/bitgesell), sorry created issue in this one by mistake

This issue names no files, tests, or specific change; it is a bounty announcement for the separate github.com/bitgesellofficial/bitgesell repository. Start by reviewing that repository and its open work to identify a concrete, reasonable pull request. Done would require an approved PR that meets the bounty rules, but this issue alone does not define a suitable scope.
