BTC 15-minute increase of 0.79%: ETF capital net inflow and institutional buying drive short-term rally
On March 4, 2026, from 06:30 to 06:45 (UTC), BTC gained +0.79% in 15 minutes, with a price range of 68123.1 to 68672.3 USDT, achieving an 0.81% amplitude. During this period, trading volume significantly increased, market attention rose, and volatility exceeded the intraday average, reflecting active short-term capital and heightened trading enthusiasm.
The main driver of this movement was the continuous net inflow into US spot BTC ETFs, especially single-day capital inflows led by major institutions (such as a peak of $458 million in early March), which pushed the spot market price upward rapidly. Institutional buying and pre-market ETF capital deployment served as direct catalysts for BTC’s surge during this period. Investor confidence was restored, and ETF inflows boosted market sentiment, supporting a breakout in price.
At the same time, technical resonance also intensified volatility. BTC found support after retracing to the 200-day SMA, MACD narrowed in negative territory, RSI rebounded from oversold levels, and short-term resistance levels were broken, triggering accelerated participation from quantitative and algorithmic funds. Improved macroeconomic conditions, global risk-averse capital flowing into cryptocurrencies, and increased risk appetite, along with net inflows into other crypto ETFs, amplified sector-wide resonance effects. Although no large on-chain transfers were detected, internal market capital battles remained fierce.
Volatility risk should be monitored, as rapid corrections may follow short-term anomalies. Future focus should include ETF capital flows, key technical support and resistance levels, on-chain activity, and macro policy changes. Users should strengthen risk management during high volatility periods, continuously track real-time market data and capital movements, and stay updated on short-term trends.
