From 16:30 to 16:45 (UTC) on February 26, 2026, the BTC spot market recorded a -0.61% return, with prices fluctuating between 66,912.7 and 67,455.0 USDT, with an amplitude of 0.80%. During this window, market attention increased, and high-frequency anomalies triggered short-term cautiousness among investors. Liquidity was ample, but volatility intensified.
The main driver of this anomaly was large on-chain fund transfers to exchanges, raising concerns about selling pressure. At the same time, the pace of ETF capital inflows slowed, and the ability of spot buying to absorb selling pressure decreased, further exacerbating price fluctuations in a short period.
