Are you looking for bounty campaigns that pay in BTC or the campaigns that pay in alts? Leaving campaigns like chipmixer and fortunejack aside, I feel the payment of IOST campaign is very good. You can earn up to 150$ a week if you are a Hero/Legendary member and the pay rates for other rank members is also good. It is managed by a very reputable manager - MadZ. I feel it is the best bounty campaign going on right now and the fact that project is also fairly good gives me lot of hope that it would be further extended.
Apart from this, Byteball's signature campaign has 9 empty slots as of today, and Datecoin is going to be extended for another week.
So you do have a lot of choices in hand. Choose the one you like.
