Yes, bounty camapigns are more and more popular. But now it is not easy like earlier to get big profit. So if new people will be want achieve satisfact profit, will be must hard working for this. In my opinion it will not be problematic for us
It is not a problem when there are too many participants in bounty campaign. More participants more popular the project. There are many bounty hunters in social media now. When google ban crypto ads, bounty participants are really important to an ICO project. Don't worry about that.
Not many ico limit their participantd in signsture campaign and in FB and Twitter too.
It is advantage to the ICO company if there are lot of participants so there coins would be quickly known to people. every bounty participants want to earn for free from joining campaign
