I also noticed a reduction in the bounty, and most good and solid projects no longer have a bounty program.
Hopefully everything will return as before, as the crypto price can be raised again later.
I often see it, some project think that bounty hunters did no big deal in promoting their projects, so they took another way to advertise it. Some of the bounty hunters also often cheating in doing it, because of that they don't respect the bounty hunters anymore.
This is a mutual process. When most of the projects are free to change the rules, freely extend the reward period, and even end up not paying, I think most bounty hunters will not respect the bounty project side because there are some rogue bounties are really not worthy of respect.
