Normally a bounty campaign should start parallel or even before ICO starts, so that you can attract more potential investors. They are still organizing the bounty campaign and the half of the ICO is already finished then.
Not sure what you are on about as MAY had many people here early on without any bounty campaigns but over time people decided to sell up and leave because clearly the dev isn't doing anything with developments. I haven't heard of any bounty campaign so I think you are posting in the wrong thread unless I have missed something here?
