There are many projects and it is very difficult to choose the project that is the best and proven to pay.
The prize manager has an important role to play in every project, as they must have a team that will check every detail of the information, team members, and authenticity of the project whitepaper. Bounty participants are free to choose and accept each bounty rule, otherwise I will leave the bounty if I think the project team always changes the rules from the rules they have made
