I got 240$ one of my easy bounties. It took few weeks to fulfill the tasks. We'd better to participate bounties as much as possible if we want to make some money.
You're lucky though since not all bounty campaign succeeds on their projects. Well, my first earning through bounty campaign is just a small amount but until now I didn't convert it since I know that coin will succeed. Your bounty profit will depend on the project you get in, so better to review the campaign before joining and don't expect that you can get the value in just a period of time.
