What is not a professional service?

Could you elaborate on what you mean by "What is not a professional service?" in the context of cryptocurrency and finance? Are you referring to activities or services that do not meet industry standards, lack proper qualifications, or simply don't fall within the scope of professional financial advice or management? It's important to understand that a professional service in this field typically involves expertise, ethical practices, and compliance with relevant regulations. So, any activity that lacks these elements might be considered non-professional.
