And there is! In order not to talk about the fact that the bounty lost their relevance - I do not believe it. So I myself am a user and I find many projects precisely because of the signatures that forum members wear.
You're right. Look at today's forum. It seems that one half is signed by the fork of Ethereum, and the other half of the participants wore signatures of the fork of the Waves.
Users feel that the project will be successful, respectively, participate in the desired bounty program.
