Actually the allocation for the current situation of bounty was to small and joining in bounty is such a matter of being lucky because most of them was fake or running for none and they use us for gaining them,so for me bounty now was totally different from the other years.
Not all bounty campign like this. I am believe many campaign worth to join because the project are good, thats why we should make research first about the project before join. Beside that, many project need more time to grow and sometimes developers team need negotiation with exchangers
