BTC plunges 0.66% in 15 minutes: MicroStrategy’s first sale of BTC, combined with institutional fund outflows, triggers selling pressure

From 01:15 to 01:30 (UTC) on June 4, 2026, BTC saw a sharp drop of 0.66% within 15 minutes, with a price range of 62,575.8 to 63,138.0 USDT and a volatility of 0.89%. Market volatility noticeably accelerated, and a technical pullback appeared in the short term.

The main driver behind this move was MicroStrategy’s first sale of 32 BTC since December 2022, worth about $2.5 million. As the world’s largest corporate Bitcoin holder, Strategy broke its core narrative of “never selling,” triggering a crisis of market trust. Michael Saylor, the company’s executive chairman, had previously said it was “possible to sell some BTC to send a signal to the market that we have already done so,” and the move is seen as a deliberate strategic adjustment, directly impacting market sentiment anchors.

In addition, multiple factors resonated together. First, ETF flows continued to see sustained outflows, with weekly outflows totaling $1.44 billion, the largest withdrawal since 2026, breaking the prior two-month streak of inflows. Second, geopolitical risk has been heating up: Iran has paused ceasefire talks with the United States, putting broad pressure on risk assets, with Bitcoin down by about 4% on the day. Third, the Fed maintained a hawkish monetary stance; the probability of a rate cut in June is zero. The market has even begun pricing in expectations of rate hikes, and a strong ISM Manufacturing PMI—the best since May 2022—reinforced tightening expectations. On-chain data shows the number of whales fell from 1,285 in May to 1,279; net positions of long-term holders declined 7.69% to 39,049 BTC. Key technical support levels were lost, triggering $1.76 billion in leveraged liquidations and creating a negative feedback loop.

Current market volatility risk remains high. Pay attention to whether support near $65,000 can stabilize, changes in institutional capital flows, and developments in the geopolitical situation. Investors should be alert to the risk of further downside in the short term, and are advised to monitor on-chain fund movements and macro policy signals.
