And what you do not like bounty paid in bitcoin or ethereum? If you hit on a bad manager and you do not pay, it does not mean that all such bounty bad. In all, in which I participated were normal payments.
I have the same thoughts. Bad experience in participating in a bounty program and not getting paid will not be able to determine that all bounty projects are not feasible. There are still many bounty programs that pay and provide good profits. This depends on the ability to choose it.
