I exclude the signature paid because the escrow system, the campaign good, because they paid with a fixed rate, went other bounty paid with alt token/coins who dont have a rate.

However, the conclusion of choosing the project "why the reason this bounty was good" was no guarantee at all. The @OP explained why the project its good just because of the bounty hunter it's reputable, not every bounty with reputable bounty manager its success it's just for helping due diligence process.
