I would sell my avatar space but only for a very high bidder. I wouldn't give up my avatar for cheap as animated avatars are no longer allowed.
How much high price are we talking about?
I do like animated avatars and I think some members would pay or donate just to get animated avatars back in profiles, but maybe new epochtalk will enable that... in 2030 maybe

I don't think I would be interested in anything less than 1btc/year. Whatever company wants it gets some value over an extended period and I get some compensation for losing my avatar forever.
Epochtalk?

That's never gonna finish.
