The span of these bounty campaigns usually puts me off because it get me bored and loss of interest due to the waiting time to get my tokens well I have no option hence I have to participate in a reliable bounty managed by a trusted manager.
I try to work with trusted managers in 70% of my bounties and leave the remaining 30% for the rest of the bounty. It often happens that well-known managers have small payments and a lot of people in the company. Beginning managers, on the contrary, because of lack of interest, the number of participants is not large, so you can get good money.
