In my opinion, the perfect ICO bounty campaign will be managed by a famous manager and have a big community to support any problem. I currently joining AIGO and I see that this ICO project is very potential and make me believe that I will earn a big profit when ICO end.
Even if the campaign manager is not so famous but when you check his background,he has made successful bounties so it would be a proof that this bounty campaign is a legit and will make a positive outcome in the end. Honestly there is no perfect bounty campaign as well as with a perfect manager, but if the team behind the project are united and share the same integrity, then we can conclude that the project will have a successful outcome.
