BTC drops sharply within 15 minutes by 0.64%: ETF fund outflows continue and support levels break in tandem, triggering short-term sell pressure

From 06:15 to 06:30 UTC on June 5, 2026, BTC plunged 0.64% within 15 minutes, falling from 62,263.6 USDT to 61,145.7 USDT, with a 1.80% range. The move occurred during the transition period between the Asia market about to open and the close of the Europe/US market, when liquidity is relatively thin, causing sell pressure to be significantly amplified.

The main driver of this volatility is sustained, large-scale outflows from spot ETF funds. Data shows that in the first week of June 2026, Bitcoin ETFs saw record outflows of more than $3.4 billion, the highest weekly outflow since the introduction of ETFs in 2024. ETF redemptions require selling BTC spot, directly increasing market supply and creating persistent downward pressure. Meanwhile, on June 2, Mt. Gox transferred 10,422 BTC (about $739 million) to a new wallet address, and whale addresses sending BTC to exchanges have raised potential selling expectations; CryptoQuant data shows whale activity has risen to a ten-month high.

In addition, the breakdown of key technical support levels triggered programmed selling. After the price fell below the 64,677 Fibonacci support level at 0.786, the RSI in an extreme oversold state (18.20) indicated that market sentiment is extremely fragile; automated execution of sell orders further intensified the selloff. Geopolitical risks (escalation in the U.S.-Iran situation leading to about $1 billion in crypto liquidations) and funds rotating away from crypto as institutional capital shifts to AI stocks formed supplementary negative factors. With multiple bearish signals converging during a low-liquidity period, a resonance effect emerged.

The market is currently in an extreme oversold state, and there may be a short-term technical rebound. However, if ETF outflows continue and the price effectively breaks below the $64,677 support, it could further test the $59,715 level and even the $50,000 range. Investors should watch ETF fund flows, whale on-chain behavior, and macro policy developments, and remain alert to the risk of amplified volatility under low-liquidity conditions.
