The current 30-minute line fluctuation is due to the tug-of-war between these two forces:
Retail investors and institutions are reducing positions on the ETF side (negative outflow) VS large holders are continuously withdrawing from the exchange (positive outflow).
The price is currently hovering around $66,600; if the net outflow data of the ETF further narrows within the next 24 hours, combined with the continued decline in exchange inventory, BTC is very likely to complete a violent surge after a "short trap". $BTC
