Note, the daily mining rate decreases as more ZOO warriors join in as the mining rate is inversely proportional to the total hash power. As the total hash power increases, the mining rate decreases. Thus, the more cards that are minted and the more players that join will lead to a decrease in the mining rate. It is impossible for the mining rate to reach 0 however, just like Bitcoin, ZOO mining will become scarce as time progresses.
