BTC 15-minute increase of 0.77%: Institutional ETF funds strongly flow in, leading the short-term rebound

Between 07:45 and 08:00 (UTC) on March 4, 2026, the price of BTC experienced rapid short-term fluctuations, with a return of +0.77%. The price ranged from 68,885.0 to 69,655.7 USDT, with a volatility of 1.12%. This movement was accompanied by increased spot trading volume, attracting market attention and intensifying volatility.

The main driver of this fluctuation was the continuous net inflow of funds into the US spot Bitcoin ETF, reaching $458 million in a single day. Institutional large holders concentrated their purchases, pushing BTC to rebound strongly in the short term. ETF funds were directly invested in long positions, reflecting strong confidence from institutions in the current range. On-chain monitoring showed multiple large BTC transfers to mainstream trading platforms during the fluctuation window, with some whale accounts actively adding positions. Order book buy orders increased, and spot funds dominated the market.

Additionally, geopolitical risks, especially tensions in the Middle East, along with increased volatility in traditional assets like US stocks and gold, prompted some funds to seek safe-haven assets in BTC. Market sentiment indicators, such as the fear and greed index, were at extreme fear levels, with retail funds continuously flowing out while institutions increased their holdings against the trend, creating structural divergence and further amplifying market volatility. Simultaneously, ETF fund inflows and the rebound of the US market premium index indicated a recovery in demand.

Caution is advised regarding the short-term volatility driven by institutional funds. If ETF inflows slow down or macroeconomic conditions worsen, there could be downward pressure on prices. It is recommended to continuously monitor key data such as ETF fund flows, large on-chain transfers, and market sentiment indicators, along with support and resistance levels, to prevent sudden market shifts.
