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.
