Just like other NFTs, the overall value of Castle Overlord NFTs is influenced by their scarcity in the market. By limiting the amount of NFTs in circulation, this value can be maintained and even increased as time passes on. We plan to offer rewards for players who are willing to hold (stake) and not sell their NFTs for a certain period of time. These rewards consist of various consumable items that players can use to gain advantage in the game. More details TBD.
