BTC drops 0.66% over 15 minutes: whale reduced holdings and derivatives short positions resonate, intensifying selling pressure

2026-04-01 13:30 to 2026-04-01 13:45 (UTC), BTC dipped 0.66% in the short term. The price ranged from 67,950.1 to 68,682.1 USDT, and the 15-minute volatility reached 1.07%. During this period, market fluctuations intensified; major exchanges saw increased attention and trading activity warmed up.

The primary drivers behind this abnormal move were whale concentrated selling observed on-chain and unusual capital flow. The data clearly shows that between 13:30 and 13:45, major BTC whale addresses saw net outflows of 2,300 BTC. Multiple individual transactions totaling over 1,000 BTC each flowed into exchange hot wallets, accompanied by a noticeable amplification of net inflows in the derivatives market. The funding rate held at -0.014%; short positions were willing to pay fees for borrowed capital, and the persistently negative funding rate reinforced downside expectations, with selling pressure immediately intensifying. The negative funding rate range expanded, and the continued negative value strengthened the downward outlook, leading to increased selling pressure.

In addition, the derivatives market structure also saw longs/short-term funds actively exiting or being forced out by stop-losses at the same time. Open interest fell quarter-over-quarter from the previous period to 48.09 billion USD, further shrinking market liquidity. The long/short ratio in derivatives dropped to 1.04, and the negative funding rate range expanded—together indicating the market sentiment is becoming more cautious. Large on-chain transfers caused network fees to rise temporarily; multiple factors converged to amplify short-term BTC price pressure.

In the current environment, short-term volatility risk is increasing. It is necessary to monitor on-chain large address movements and the derivatives funding rate trend in a timely manner. Key support levels and changes in long positions remain the focus for subsequent observation. If whales continue to flow out or the market sees more long liquidations/stop-losses, BTC may face greater downside adjustment pressure. Please keep monitoring market developments and stay alert for a new round of volatility triggered by a sudden drop in liquidity or unexpected macro events.
