Bitcoin ETFs see strongest demand since spring as traders test the $80,000 breakout

Spot Bitcoin exchange-traded funds in the US have attracted their strongest wave of demand since the spring, raising questions about how long the cryptocurrency can hold above the $80,000 mark. On August 24 alone, US spot Bitcoin ETFs posted net inflows of about $337 million, capping a six‑session streak of positive flows. Over the course of a week, total ETF assets swelled roughly 25%, climbing from about $79 billion to nearly $99 billion.

BlackRock’s iShares Bitcoin Trust has been the main magnet for capital, drawing between roughly $160 million and more than $500 million on several trading days between August 17 and 24. The surge in demand has coincided with a sharp move in spot prices, as Bitcoin powered back toward $80,000, triggering both profit‑taking and short‑covering among leveraged traders.

Market strategists stress that this leg of the rally is being driven largely by “off‑chain” money – investors who access Bitcoin via securities accounts rather than holding coins directly on the blockchain. That makes it easier for institutions and high‑net‑worth individuals to rotate capital out of stocks or bonds and into digital assets, potentially amplifying volatility in both directions. While sustained ETF inflows could help Bitcoin consolidate above the $80,000 level, the same structure means redemptions can accelerate quickly if sentiment turns, leaving the market vulnerable to abrupt reversals.
