I read a lot of useful information, I think that all this will be very useful in the near future, but I still think that bounty does not have any useful effect for the project, because bounty is a very small percentage.
I can say that you are wrong. What gives generosity? First is free advertising. Secondly, those who are passionate about cryptocurrency can also invest in the project. The more information on the Internet, the easier it is for investors to find and study projects. So this is my opinion.
