I can see that on the miners in a bull market. Right now I know of miners who are selling their full rewards as soon as it hits to make sure they have fiat gains. It doesn't make sense to me but I guess they assume they'll be able to buy back in cheaper from here.

I have to fully agree that burning has no value to tokens. I made this mistake with SPORTS when we rolled out a program to pay people to burn. It might have encouraged more to get burnt but it never created a net burn or a culture towards more burns. It just left a new net inflation supporting the rewards for it.
