Bitcoin opened at $78,559 on Tuesday, 1.1% above Monday, then slid to $77,946 by mid-morning as rate expectations kept resetting. CME Group's FedWatch tool now puts a 25 basis point hike at 66.4% against 33.6% for no change, a near-complete inversion from last week when economists had it at 60.4% unchanged. Crypto, gold, and silver all followed the same shape Tuesday morning, firmer opens giving way as the September meeting comes into focus.
