It is uncertain to receive payment from Bounty. Some bounties are successful and some are not. Each bounty has a different budget. Successful bounty pays some but unsuccessful bounty can't pay hunters. We have to accept it.
Almost every day new bounties are coming. Some of these bounty budgets are escrowed. You can join these bounties. Because they are very sure to get the payment.
Yes, agree here because today I was reading some social media channels where some good number of members were complaining about payments and admins were not interested even not giving any replies it's now usual business for many because they are coming with different ID's as bounty manager after completing task suddenly they are disappeared which is worst for many as they are giving some good time and effort for these bounties.
Right now we need some better check in bounties because if they were able to check few things about this surely they are going to have some better end because teams and projects both are very important for these bounties.
