BTC drops sharply in 15 minutes by 0.49%: Institutional spot ETF outflows for 13 straight days hit a record, triggering short-term selling pressure

From 23:30 to 23:45 (UTC) on June 21, 2026, BTC rapidly dropped within 15 minutes, with a return of -0.49%. The price ranged from 63,305.4 to 63,664.0 USDT, with a volatility of 0.56%. This sharp short-term selloff occurred amid extremely fragile market sentiment, further amplifying short-term fluctuations.

The main driver behind this anomaly is the continued outflow of institutional funds. In early June 2026, BTC ETFs saw a historic streak of 13 consecutive days of outflows, totaling a net outflow of $4.33 billion, setting the longest outflow cycle since the ETFs were launched in 2024. Institutional investors, as key marginal buyers in the spot market, reduced demand directly through large-scale net selling, putting downward pressure on prices.

In addition, market sentiment indicators worsened in parallel, intensifying the resonance of sell pressure. The Crypto Fear and Greed Index has fallen to 13, indicating the market is in a state of “extreme fear,” with weak willingness to absorb buy orders. Meanwhile, on-chain cost structure shows a realized price of about $53,796, leaving roughly 16% upside room versus the current price, providing shorts with a downside target range. Derivatives market data shows traders are broadly bearish on BTC’s near-term outlook, further reinforcing short-term selling momentum.

Current volatility risks remain. Watch the support level near $63,000 and changes in institutional fund flows. If ETF outflows persist, it could trigger a chain of selloffs; conversely, if macro sentiment improves or dip-buying emerges, prices may stabilize. It is recommended to monitor the evening institutional holdings report and on-chain fund flow changes, and stay alert for liquidation risks from leverage.
