Seems like there are more bounty campaign are extending their campaign period due to not reaching their soft cap. Are you still continuing the campaign though it is extended?
It seem their marketing or their product not gain investors' attention. Then their project will shut down for not reaching soft cap.
IMO, I will stop their bounty campaign but still keep following their bounty for all stakes I already got in order to know they will pay or not for all bounty.
Only signature campaign that will disqualified your signature if you stop doing bounty campaign. So if you want to stop, make sure you are not be disqualified from bounty campaign
