Citadel CEO Ken Griffin has raised concerns about the U.S. dollar's diminishing role as a global safe haven amid a surge in gold and Bitcoin prices. Gold futures recently surpassed $4,000 an ounce, while the U.S. Dollar Index has declined by approximately 10% this year. Griffin highlighted a trend of investors shifting towards hard assets like gold and Bitcoin to hedge against monetary debasement. Bitcoin reached a new all-time high of $126,000 on October 7, reflecting increased investor interest in alternative assets.
