What qualifies as a professional service?
Could you please elaborate on what exactly constitutes a professional service in the realm of cryptocurrency and finance? Are we referring to specialized consulting, advisory roles, or perhaps a blend of both? Is it the expertise and experience of the service provider that sets them apart, or the tailored solutions they offer to clients navigating this complex and dynamic landscape? I'm particularly interested in understanding the criteria that define a service as 'professional' in this context, given the unique challenges and opportunities present in the cryptocurrency and finance industry.
