Viewing multiple projects has also run participant restrictions. And the result they get more coins when compared to projects that are not restricted participants. We can see the Bounty project with Bitcoin payments. Participants are also limited but only with an account above full members who can join.
But all the definite decisions in the hands of Bounty managers. Seeing many altcoins of course we must also be intelligent in determining the Bounty project. So, despite the many bounty participants, we can still get good results.
the big problem is that bounty hunters work with projects without doing any project analytics. very often they do promotion for scam projects and many investors can be scammed
