now you have to be more selective in choosing which bounty you will follow, lower your expectations and follow all of them (bounties that pay tokens) if you can because maybe one of them will pay you. but if you want to get a bounty with a definite payment then look for a bounty in the "service" section (which pays bitcoin) because it is more certain to get paid every week.
The difference between bounty and a campaign for BTC payouts although the working method is not much different for the purpose of promoting the project, so if it's not feasible to join the campaign on the service then look for opportunities on the bounty, I think there are some good bounties in progress so take the time to check the details
