Very nice Paula! That GIF is excellent.
I think there does need to be good remuneration for the top witnesses as the responsibility for the blockchain is in their hands. It would be good to understand what the approximate costs are for running a witness as well to complete the picture.
Glad you liked the GIF.
The cost to witnesses, well there is a cost for a node, but they the time and effort also put to being a witness is a lot greater me thinks!
