This is just a suggestion devs but I think the participation for new members for bounty campaign should be closed. I think that the period for the bounty is very long and now that they're too many participated because of that long period of time that it is open, the bounty allocated that will be shared will be very small when it is distributed to the members.
I think that it does not negatively affect the development of the campaign. In total, we have a free market and founders can do whatever they want. Besides, nobody promised their members that they would be the only ones in the campaign.
