What is Coinbase one?

Could you please elaborate on what Coinbase One actually is? I've been hearing a lot about it recently, but I'm still a bit hazy on the details. Is it a new type of cryptocurrency exchange? Or is it more like a comprehensive platform that offers various crypto-related services? I'm also curious about its unique selling points compared to other crypto platforms. Could you highlight some of its key features and benefits for users? Additionally, how secure is Coinbase One, and what measures does it take to protect user funds? I'd appreciate your insights on this emerging crypto offering.
