The Federal Reserve's rate decision, due later Wednesday, has emerged as the dominant catalyst shaping crypto market sentiment this week. Ether, the second-largest cryptocurrency by market value, moved somewhat more sharply than bitcoin during the same period. Broader cryptocurrency market data showed modest overall improvement heading into Wednesday. Bitcoin's dominance within the broader crypto market held steady at approximately 56.3%, while ether accounted for roughly 10.2% of total market value. Trading data suggested bitcoin has largely oscillated within a defined range in recent sessions, generally trading between roughly $62,700 and $65,500.
