What is the use case of Raydium?

So, can you tell me a bit more about the use case of Raydium? I've heard it's a popular decentralized exchange on the Solana blockchain, but I'm curious about the specific scenarios or applications where users might find it most beneficial. Is it mainly for trading Solana-based tokens? Or does it offer any unique features or services that set it apart from other exchanges in the space?
