That the main problem some ico use to have after suffering particpating in there bounty you won't get paid some will tell you that the have extend there date from extending there date you will not hear anything from them again.
Well, those bounty campaigns are having blood bath right now, sometimes we just been manipulated for promoting scam ICO and got red trusted. Sometimes we promoted a real ICO but didnt reached the softcap, when an ICO reach its target, they coins suddenly drops in price after got listed on exchangers. Its kinda frustrated for us right now. Maybe the golden era of bounty and airdrops already passed? Thought?
