Fixed supply, no mint, and three ways to use it. Every use burns or is funded by a burn.
Burn to add a quarter of a rig's hoodrate for one whole epoch, up to four times for double weight. Each stack in the same window costs twice the last.
Five points of every rental accumulate and are spent buying $RATE on the open market. What comes back is burned.
Holding $RATE cuts the price of a rental. The discount comes out of the operations share, never out of the coffer or the bounty.
