# Backers Backers are crypto enthusiasts, speculators, farmers, apes and degens. They use their experience to decide on which project and at what time to invest their [LUNAR](/m00n-city/lunar-token.md). This is done by buying and selling [APP tokens](/m00n-city/app-tokens.md) from their bonding curve smart contracts. In this way backers' collective intelligence will accelerate the development of the most valuable features or projects. Backers can use the [Ideas](/m00n-city/ideas.md#app-marketplace) to find and buy [APP tokens](/m00n-city/app-tokens.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
