Bounties is all about luck this days, staying away from scam projects is another topic but I'm here to clarify that listed bounties don't have anything to do with payouts every time, meaning that just because a bounty project is listed on exchange doesn't mean you will get paid, hunters can prove me wrong, few listed bounties already disappoints.
That's true.
A tradable bounty campaign is no guarantee that you will get a large profit. Especially if the volume is very small, it's only false hope. We can not really know what will happen in the future, many have experienced this, the campaign which was previously considered not promising turned out to give a big profit one day.
An analysis is indeed necessary, but do not expect too high, it could be that luck is not on your side. Just do the work as a bounty hunter calmly, don't be greedy. Use the opportunity as you can, however, the quality is more important than quantity.
