Exactly most bounties now are Defi, so there is no need for KYC. Anyone can use UniSwap to exchange tokens. If a bounty ask for KYC then there must be an dark intention of getting your information. I dont see the reason of asking for KYC. As long as the bounty hunter are doing their task right why ask for KYC!
Honestly, KYC or AML is only needed when it comes to partners to buy, sell and exchange new projects through ICO, IEO, IDO,... But now i think it's not so important for everyone. people who started using DEX more and also looking for opportunities to add their assets by investing in new (not scam projects) projects. Also, I want to talk to OP about monetization platforms like bounty, give DAO Maker a look.
