BTC drops 0.45% in 15 minutes: Whale concentrated transfers into exchanges stack up sell pressure while leverage withdrawals amplify the pullback
From 17:00 to 17:15 (UTC) on 2026-04-17, BTC saw a brief drop. The return rate recorded was -0.45%, with the price ranging from 77354.3 to 77916.9 USDT and a swing of 0.72%. During the event, market attention warmed up, volatility intensified, and spot market liquidity changed significantly.
The main driver of this price anomaly was that whale wallets concentrated transfers to exchanges. In a single 15-minute period, the exchange inflow surged to 11,000 BTC, reaching a new high since December 2025. The average amount deposited per transaction was as high as 2.25 BTC, indicating that large holders chose key price levels to concentrate and release their positions, clearly lifting sell pressure. At the same time, BTC futures open interest fell to a 14-month low of $841 million, as leverage funds exited sharply. The spot market’s pull on price fluctuations became the main factor, further magnifying the impact of whale trading.
In addition, although ETF funds had a net inflow with a hedging effect—bringing the April cumulative inflow to $5.651 billion—within this anomaly window they were not able to fully absorb large sell orders. The spot market mainly relied on institutional buying to digest the selling pressure, and overall risk appetite contracted. On-chain data shows that 41% of the BTC supply is in a loss-making range, and some holders who bought at lower prices face take-profit and stop-loss pressure. With multiple factors converging, short-term tension formed among exchange inflows, leverage withdrawal, profit realization, and institutions’ ability to absorb, increasing the magnitude of spot volatility.
Short-term risks are worth watching closely. Users should closely monitor core indicators such as the subsequent exchange inflow volume, the pace of ETF net inflows, and futures open interest. If whale sell orders still have not eased and ETF inflows cannot accelerate in step, the BTC price may remain under sustained pressure. Users should focus on on-chain transfers and changes in major holders’ positions, watch the spot market’s key support ranges and trading structure, obtain more market information in a timely manner, and stay alert to risks brought by sharp volatility.
