What is Google Gemini used for?

I'm curious, could you please explain to me the purpose and intended use of Google Gemini? I've heard it mentioned in the context of cryptocurrency and finance, but I'm not entirely clear on its exact functionality. Is it a platform for trading digital assets? Or does it serve a different purpose within the blockchain and finance industry? I'd appreciate it if you could provide a concise yet comprehensive description of Google Gemini's primary applications.
