Cameron Winklevoss, cofounder of Gemini, has revealed that David Sacks, the US crypto and AI czar, is expected to lose up to $1 billion in potential crypto gains over the next four years. Sacks sold all his cryptocurrency holdings, including $85 million of personal assets, to avoid conflicts of interest before assuming his role. Despite leading significant policy shifts in the US crypto landscape, including the establishment of a Strategic Bitcoin Reserve, Sacks will not benefit financially from these changes. His actions have sparked controversy, with critics accusing him of unjust enrichment, but Winklevoss defends Sacks, highlighting his commitment to ethical governance.
