# 1. Key Currency - MARBLE

MARBLE is the Key Currency  used within the Insta#LAND platform, providing a core mechanism for the platform's development. Users can engage in various revenue-generating activities through the platform, earning MARBLE as a reward or through mining. MARBLE serves as the main payment method for economic activities such as purchasing, trading, traveling, producing, and governance within Insta#LAND, connecting to the platform's essential value.

The non-fungible tokens (NFTs) in the Insta#LAND ecosystem, such as LAND, Asset NFTs, and Utility NFTs, are linked and traded through the exchangeability of MARBLE, providing a channel for participants to realize profits from ecosystem economic activities.

MARBLE plays a crucial role as the base currency within the Insta#LAND ecosystem. The platform aims to incentivize participants to create value and improve the quality of travel products and services, ultimately enhancing the overall travel experience.
