From 17:15 to 17:30 (UTC) on May 26, 2026, BTC急跌ed 0.55% within 15 minutes. The price fell from 76,477.8 USDT to 76,053.1 USDT, with an amplitude of 0.56%. This period sits at the handover between the end of the London trading session and the early opening of the New York session. Buy and sell order book depth was relatively thin, and weak liquidity amplified short-term volatility.
The main driver behind this abnormal move is the combined effect of institutional selling pressure and sudden fund movements by giant whales. Forbes reported disclosures indicating BlackRock is carrying out large-scale sell-offs. At the same time, the well-known Bitcoin whale Garrett Jin has been continuously depositing BTC to a major exchange. In recent months, he has accumulated deposits of over 11,000 BTC (about $760 million), which is seen as a signal of preparation to sell. Coordinated distribution by institutions and whales directly increases market supply pressure. In a time window where liquidity is comparatively weak, it triggers a sharp short-term drop.
Second, on-chain abnormal activity and macro uncertainty are creating a resonance effect. From April to the middle of May, on-chain data shows whale activity was extremely active, but spot trading volume shrank to a low point of $19 billion. A clear “price–on-chain activity divergence” emerged. This undercurrent setup had already been building selling pressure prior to this move. In addition, ongoing tariff policy uncertainty throughout 2026 and persistent geopolitical risks continue to weigh on market confidence. Institutional investors’ risk appetite declines, leading them to prefer holding safe-haven assets such as USD or gold. On the technical side, OBV continues to trend downward and formed a “roller-coaster top” reversal pattern. The TBO signal is at a critical state, further amplifying short-term sell pressure.
There are still volatility risks. Investors should watch whether the key support level of $76,000 can hold, as well as on-chain fund flows and changes in institutional holdings. If institutional selling continues, the short-term sell-off may probe lower further. Near-term macro news (tariff policy progress, geopolitical developments) and ETF fund flows will be key indicators to monitor. Users should remain alert to “needle-like” risks during periods of thin liquidity.
