Bitcoin breaks $66k as US debt hits $39.5 trillion creating Bitcoin’s next liquidity test for August 3

US gross federal debt reached $39.489 trillion on July 15, leaving roughly $511 billion before the $40 trillion threshold, and this debt total strengthens Bitcoin's fixed-supply argument. Treasury currently expects to borrow $671 billion in privately held net marketable debt during the July-to-September quarter, with the estimate built on a $950 billion end-of-September cash balance.
