The most painful experience when promoting a bounty project is thinking you made a right choice by removing the signature of the project you are promoting presently for another project that you think its better and later on? 
The first project you are promoting get listed and doubled in value ,how will you feel? Damn! The fact is bounties are unpredictable sometimes ,no one can predict the end results
it's hard to predict the gift of a campaign even more so when the campaign has a high enough value but when we receive the gift the value becomes smaller,Maybe even some of the hunters often leave campaigns to join other campaigns that have more value. But in the end the gift value is quite low, This is the importance of patience and strong belief in joining campaign programs The first project you are promoting get listed and doubled in value ,how will you feel? Damn! The fact is bounties are unpredictable sometimes ,no one can predict the end results
