Paul Tudor Jones did it for hedge fund managers. Michael Saylor and Jack Dorsey did it for publicly traded companies.   Now, Marty Bicknell is doing it for RIAs and he discusses it with me on my new podcast.   Once called “rat poison squared” by Warren Buffett, bitcoin is now going mainstream. After a tumultuous 12-year existence punctuated by head-spinning bull markets, devasting declines, exchange hacks, and its use in criminal activities, bitcoin has grown into adulthood.   Bicknell recently announced that his firm, the $35 billion AUM behemoth Mariner Wealth Advisors, will offer bitcoin to its clients through a separately managed account run by Eaglebrook Advisors.   To date, only a small number of intrepid advisors including Morgen Rochard, Jackson Wood, Adam Pokornicky, Tyrone Ross, Adam Blumberg, and Isaiah Douglas have done the pioneering work of understanding bitcoin, figuring out the compliance and operational details of offering it, and presenting it to their clients as part of a thoughtful asset allocation.
