BTC 15-minute increase of 0.61%: On-chain whale funds concentrated inflow driving short-term rebound

From 18:30 to 18:45 (UTC) on February 26, 2026, BTC price fluctuated between 66,848.7 and 67,381.8 USDT. During this 15-minute period, the return was +0.61%, with an amplitude of 0.80%. Market attention rapidly increased, short-term trading volume expanded accordingly, and upward price movements became evident. Volatility was higher than the average for the same period, reflecting active short-term capital and intensified market sentiment.

The main driver of this movement was a concentrated influx of whale funds on the blockchain within a short timeframe. Key on-chain monitoring data showed that whales (holding ≥1,000 BTC) conducted large transfers and position adjustments during this window, with multiple channels indicating significant on-chain buying and capital absorption behaviors, directly boosting the market. The whale accumulation trend score increased, indicating strengthened bullish sentiment, which directly pushed BTC prices higher in the short term.

At the same time, the surge in trading volume temporarily improved market liquidity, with large buy orders filling liquidity gaps. Some market depth shortages further accelerated rapid fluctuations. Additionally, ongoing macroeconomic uncertainties fueled risk-averse capital inflows into crypto assets, increasing demand for BTC. Investor confidence improved noticeably amid macro capital inflows and new whale positioning, creating a multi-factor synergy that amplified BTC’s upward price movement.

Current short-term volatility risks still require close attention. Ongoing monitoring of whale behavior, large capital flows, changes in funds on major trading platforms, and macro policy and global capital flow trends is essential. Users should be cautious of price pullback risks, watch support and resistance levels around 67,380 and 66,800, and stay alert to market sentiment and capital movements to promptly grasp market anomalies.
