FiveStars will support item trading using minerals (MNR - Mineral) in future global versions. Mineral is a cryptocurrency used for game item trading in Clayton-based DApp games. Minerals have features that can be used outside of games, unlike gold and crystal, which are common game currencies. Users can obtain MNR through in-game content (exchange) and purchase it through cryptocurrency such as Bitcoin on an external cryptocurrency exchange. It aims to assetize data through blockchain so that items obtained from specific games can be used in other games.
