What can you do with balancer?

So, I'm curious to know, what exactly can one do with Balancer? Is it just a platform for trading tokens, or does it offer more functionalities? Could you elaborate on the various use cases and features that make Balancer stand out in the cryptocurrency space? I'm especially interested in how it enables users to create and manage their own customized liquidity pools, and how that can benefit traders and investors. Are there any limitations or risks that one should be aware of when using Balancer? I'd appreciate a comprehensive overview of its capabilities and how it fits into the broader cryptocurrency ecosystem.
