LUN is not just a cryptocurrency, but a governance token that plays a crucial role in the Terra ecosystem. As a part of the Terra protocol, LUN is used for governing the DeFi platform, which aims to provide price-stable cryptocurrencies for global users. This includes voting on decisions and proposals for network improvements, updates, and new features. LUN also carries practical value, as it can be used for transaction fees and collateral within the ecosystem. Additionally, its scarcity and utility as a governance token may lead to an increase in demand, potentially driving up its value. In essence, LUN is deeply intertwined with TerraUSD (UST) and serves as a vital tool for governance and investment within the Terra ecosystem.
