BTC 15-minute decline of 0.60%: key support broken, combined with leverage deleveraging triggering short-term selling pressure

On March 11, 2026, from 17:30 to 17:45 (UTC), BTC experienced a -0.60% return over 15 minutes, with prices fluctuating between 70,515.2 and 71,317.0 USDT, a volatility of 1.13%. Trading volume significantly increased compared to the previous period, dominated by sell orders, leading to intensified short-term market fluctuations and heightened market attention.

The main driver of this movement was the breach of the key support zone at $68,000–$68,200, triggering algorithmic sell-offs and stop-loss orders, which caused a short-term decline. Additionally, high-frequency trading and quantitative funds accelerated selling pressure at critical price levels, amplifying localized market volatility.

Furthermore, the perpetual contract liquidation amount rose from $350,000 to $650,000, with some leveraged longs being passively deleveraged, and forced liquidations further pushing prices downward. Order book data showed prominent order cancellations, causing a sudden liquidity contraction, making large sell orders more impactful and creating a “waterfall” effect in the decline. On-chain monitoring indicated no abnormal large transfers or whale activities, and industry news remained stable. The macro environment was also steady, with no systemic risks detected in news or on-chain data. The resonance mainly stemmed from market structural imbalances.

Currently, BTC faces short-term liquidity pressure, with increased market focus on the $68,000 support level. If funding conditions do not quickly improve, price volatility risks remain. Close monitoring of order book depth, on-chain fund flows, and key support/resistance levels is essential, with caution advised regarding secondary fluctuations caused by high leverage.
