This is normal for now because more bounties were now replaced by social mining one. In social mining it's easier to do task and less spammy.
So you mean to say that we wouldn't get decent rewards doing bounty at this time because more bounty people are opt to do the social mining?
That's not true, Bounty is currently the best option to promote a campaign. But the current situation is not so good for bounty projects, I believe that in the future when the market recovers, bounty will surely be bustling like previous years.
