Due to bad market conditions, investors are not very interested in inviting new projects, due to which new projects mostly fail and because of this, the projects that are bringing bounty campaigns for them are not seen to be successful. That's why working in bounty campaign doesn't get any payment. So working on the bounty campaign in this current situation will be a waste of time. Because a large number of users joining a campaign cannot expect to receive large payouts.
Don't take me on offence. But I couldn't agree here on that point currently market condition is bad and that's why the investor are not very interested in inviting the new projects on bounty campaign.
Because we have already the chart the Bull season is started currently market condition was good even then altcoin season hasn't been started yet but altcoin market looks also good right now.
Now let's come to the main point, the project and not interested on bounty campaign only for the outcome like most of the bounty Hunters are now making just spam on their posts they just used copy and paste method to doing bounty campaigns and here the promotion out put result become poor even then that help them rank up on search engine. And besides currently they can do more good result by launching the airdrop campaign on telegram which has also good result. And I think these are the reason.
