BTC 15-minute sharp decline of 1.36%: whale selling pressure combined with support level breakdown triggers short-term liquidation

On May 4, 2026, from 10:00 to 10:15 (UTC), BTC experienced a sharp decline of 1.36% within 15 minutes, with a price fluctuation range of 78,599.1 to 79,877.7 USDT, and an amplitude of 1.60%. Market trading volume surged dramatically, long leverage positions were liquidated en masse, and short-term volatility was intense.

The main drivers of this anomaly were whale short-term selling pressure and the breach of key technical support levels. On-chain monitoring showed multiple large BTC transfers from cold wallets to exchanges within 48 hours before the event, with single transfers ranging from 1,000 to 5,000 BTC, directly increasing market selling pressure. Meanwhile, the $75,000 critical support level was broken, triggering algorithmic trading and stop-loss orders to be released in concentration, further accelerating the downward momentum in the short term.

Additionally, long leverage liquidations amplified the decline. Major exchanges saw over $300 million in long contract liquidations, causing forced liquidations that created a chain reaction of sell-offs. Institutional funds also withdrew simultaneously, with ETF products experiencing a net outflow of $150 million over the past two days, reflecting short-term exit by institutional investors. On the macro level, the Federal Reserve hinted at the continuation of high-interest-rate policies, coupled with the upcoming release of US CPI data, making the market sensitive to inflation and policy uncertainties. The demand for safe-haven assets increased. Furthermore, the decline in active on-chain addresses indicated weakening demand, resonating with macroeconomic pressures.

In the short term, attention should be paid to whether BTC can recover the $75,000 level, or if it further drops below the $70,000 support. Key indicators to observe include ETF capital flows, changes in exchange BTC reserves, and derivatives funding rates. Currently, volatility risk is high, and users should closely monitor macroeconomic data and policy developments to guard against further short-term adjustments.
