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
I've experienced something like that ... I left a project just to find a better one than I left ... and it turned out that the best was what I left behind ... I was very sorry at that time. and now I have never done it again ... because it was very sad and suffocating me when I saw the coin I left behind had an incredible price
