It's the worse time to do bounties without a decent job, there is no good ICO bounty campaign right now if you want to do signature campaign might as well take the gambling and gaming signature campaign, ICO bounties will become a thing of the past if investors will continue to lose money with ICO.
maybe if this condition continues we will not see bounty campaign anymore.most ico now failed and developers team prefer to held IEO in reputable exchanges.this methode was very successfull and investors satified with it.
