I think the most important thing is to participate in the campaigns of bounty managers who do their job properly.
I don't see a famous manager now, for example sylon, jamal, yahoo. I do not know whether they are retiring or not interested in becoming a manager.
many new managers, so it's difficult to set a good bounty based on manager's criteria.
I dont see sylon anyomre but jamal he is still verry active on handling bounty campaigns while yahoo is rarely managing because he is picky . he said that he will only accept legit projects although yahoo is actively managing sig campaigns that are paying in btc .
But even if how reputable the manager are , they cannot still guarantee the success of the campaign and most of all , they wont also handle the payments because their jobs is to only accept people and count their post .
