Rain Coin (RAIN) is a cryptocurrency token that operates primarily on the Polygon network. It is designed as a "meme" coin, with features that reward its holders through a unique redistribution mechanism. Specifically, 1% of every transaction involving RAIN—whether it's a buy, sell, or transfer—is redistributed to all RAIN holders proportionally to their existing holdings. This allows users to earn passive income simply by holding the token. Additionally, the project includes a daily event called "Thunderstorm," where additional tokens are distributed to holders, further enhancing the rewards.

RAIN is mainly used as a speculative asset with a focus on passive income generation. Its primary utility lies in the redistribution of transaction fees to holders and the daily distribution of additional tokens through the "Thunderstorm" event. Given its nature as a meme coin, it does not have a specific use case beyond serving as a vehicle for investment and speculation within the cryptocurrency space. The token is also traded on a limited number of exchanges, where it can be exchanged for other cryptocurrencies, particularly USDT and MATIC.
