$ROLL

The token does not
get you paid more

Every token like this ends up pointed at the leaderboard, and the day it does, the leaderboard stops meaning anything. $ROLL is kept on the owner side for that reason alone: owners pay to list, posters pay nothing.

LISTING
It lists a coin
Listing costs $ROLL. The owner who wants the crowd pays it, never the people posting — and that is the only place the token is needed.
BUYBACK
It gets bought back
Five percent of every fee on the platform buys $ROLL on the open market, for as long as coins get listed here. The bid comes from usage, not from a treasury deciding to be nice.
NOTHING
It does nothing for posters
No rank, no score multiplier, no earlier access to a pot. Holding cannot move you one place up a board, and that is deliberate rather than an oversight.

$ROLL is not launched yet. Coins get listed without it during the beta, and the buyback starts the day a mint exists. Nothing a poster does depends on the token.
