What is maverick mav?

Excuse me, could you clarify what you mean by "maverick mav"? Is it a reference to a specific individual, a term in the world of finance or cryptocurrency, or perhaps a company or organization? As a professional practitioner in the field, I'm not immediately familiar with this particular phrase. Could you provide some context or background information to help me better understand what you're asking about? Without that, it's difficult for me to give you an accurate and informative answer.
