NFTDUEL has sustainable structure for well balanced reward mechanism
$DUEL is one type of reward that is earned from Leagues in NFTDUEL. Only Players who have upgraded their accounts by owing a deck with a certain amount of NFT cards and certain amount of token are eligible to earn $DUEL by winning in the league.
Winning in the league is the one of the main ways $DUEL is produced. There is always a pool of $DUEL rewards, and that pool is constantly divided among the current winning players. This is why $DUEL earned per win is continuously fluctuating. The amount rewarded to each player always depends on the total amount of $DUEL in the pool and several other factors.
