From 09:15 to 09:30 UTC on June 4, 2026, BTC saw a -0.75% return; the price pulled back into the 62,800.0–63,340.3 USDT range, with a 0.85% amplitude. This period falls during a low-liquidity window at the handoff between Asian and US/Europe trading sessions. Selling pressure was released in a concentrated burst, causing a rapid short-term plunge.
The core driver behind this anomaly is continued outflows of institutional capital. May 2026 marked a key turning point in BTC ETF fund flows. April had delivered strong performance with $2.44 billion in net inflows, but it sharply reversed in late May—by the end of May, ETFs recorded net outflows for six straight trading days, with a cumulative outflow of $1.26 billion, setting a record for the third-largest outflow of 2026. BlackRock’s IBIT saw a single-day outflow of $448 million; ARK’s ARKB outflow was $110 million; and Fidelity’s FBTC outflow totaled $63.42 million. Large institutional investors are carrying out systematic de-risking.
At the same time, whale activity has intensified market pressure. CryptoQuant data shows the exchange whale ratio has risen to its highest level in ten months, with large holders using exchanges to transfer funds in dense bursts. Glassnode data shows BTC whale count peaked at 1,285 on May 22 before falling; within a week, it dropped by 6 entities, involving about $440 million. Long-term holder net position indicators also show that coin-age addresses holding for more than 155 days declined 7.69% to 39,049 BTC on May 28. Even more strikingly, market rumors confirming that Strategy sold BTC for the first time in years were validated on June 1, adding further pressure to already fragile market sentiment. On-chain activity also fell to a freeze-like low, further weakening market absorption capacity.
Current market volatility risk is significant. Key things to watch include the strength of support around the $60,000 psychological level, whether ETF fund flows continue to worsen, and changes in whale addresses. Short-term investors should be alert to the risk of further pullbacks that may occur amid shrinking liquidity, and are advised to closely monitor on-chain fund flows and macro policy signals.
