Bitcoin heads into Wednesday's Federal Reserve decision without two tailwinds bulls hoped would carry it back above $80,000. The cryptocurrency briefly fell below $75,000 after the US Senate failed to advance the CLARITY Act, while markets moved towards near-certainty that the Fed will raise rates by 25 basis points. Bitcoin later recovered and is now trading near $75,500. That rebound makes one level more important than the expected policy move. If buyers defend $75,000 after regulatory disappointment, 5% Treasury yields and tighter policy have already been absorbed; the reaction could reveal more about underlying demand than the Fed headline.
