1. Bounty budget, Not to big and not to small because big rewards also has a big chance for scams
We would never know the actual budget of each ICO or campaign because most of the ICOs and projects are manipulating their figures in order to attract more investors.
2. Project, check if the project have an impact for the crypto community
This is the good one, not all ICOs and projects are having good impact on our community because most of them are just bubbling "Decentralization" word on their platform like data and information centered blockchains.
3. Team, if the team has a good reputation
Almost all team members are good when we read about them on their websites, of course! who else give them discredit? checking team members isn't enough to be a good ICOs and projects.
4. Manager, check also if the manager is reputable because reputable bounty managers dont choose scam ICOs.
This is the best one. Good bounty managers are more reliable especially higher ranked bounty campaign managers than lower ranks like Newbie or Jr. Members.
Good bounty campaign managers are being followed by good bounty hunters.
