What is a Crypto LLC & how does it work?

Could you elaborate on the concept of a Crypto LLC and its operational mechanisms? I'm particularly interested in understanding the legal structure, its regulatory framework, and how it differs from traditional LLCs. Furthermore, I'd like to know if these entities specialize in any specific cryptocurrency activities, such as mining, trading, or investment. Lastly, could you provide an overview of the potential risks and benefits associated with operating a Crypto LLC?
