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
yes alright bounties is unpredictable, its only bounties of ico or eio. unpredictable from the price coins after launched and the reward we get . so for social media campaign ussually join for all bounties. but for signature campaign i join with high raise fund it for last month ago during ico still worth. 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
its different with bounties pay bitcoin or altcoins not token. because paid with bitcoin you can count about your reward so more predictable than ico
