How did inflows affect Ethereum market dynamics?

Large ETF inflows removed Ether from spot exchange inventories as tokens moved into custodial vehicles, increasing price sensitivity. Market liquidity tightened, amplifying short-term volatility risks. Historical patterns show that sustained ETF accumulation can exert upward pressure on spot prices due to reduced circulating supply.
