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
For me it is really true that almost all bounties are really unpredictable, but we can still make a good amount of profit with bounties if we can able to find a really great project like aigo, and i believe many more good projects will show up this year.
