The simple model of the bounty market is - ico lives - bounty lives, ico is dead - bounty is dead. We are at around dead position right now since July.
I agree with you that since the second half of 2018, the bounty has almost been in a state of "waiting for death".
There are still a lot of bounty, but most of these rewards are not satisfactory. If you participate in 10 bounty, then only 2-3 items may be paid, and the worst is The token you get is simply not worth the money.
