It is rewarding for sure, but you need to do your research to chose the right bounties as today most of them are scam. Additionally, to be a good bounty hunter, you need to plan accordingly, regularly update your bounty spreadsheets and post your reports. And at last but not least, you better understand the rules and requirements of each bounty and pay attention to the updates as some bounties tend to change their rules and requirements. If you miss it, you may not be rewarded or you may be rewarded with less reward. Hope this clarifies.
