BTC 15-minute gain of 0.63%: ETF positive news combined with institutional fund inflows triggers breakthrough

From 22:30 to 22:45 (UTC) on March 15, 2026, BTC rose 0.63% within 15 minutes, with a price range of 71,926.4 to 72,500.0 USDT and a volatility of 0.80%. During the same period, trading volume significantly increased, with buying dominance, market attention heightened, and volatility exceeding the intraday average, reflecting rising sentiment and active short-term trading.

The main driver of this movement was a sudden macro positive development: at 22:00, the US SEC issued an optimistic statement regarding Bitcoin ETF approval progress, directly boosting market sentiment and increasing risk appetite. Meanwhile, on-chain data showed multiple large transfers exceeding 500 BTC flowing into major exchange hot wallets, mainly from institutional accounts in the Americas and Asia, with a net inflow of up to 2800 BTC, pushing the price short-term breakout.

Additionally, BTC broke through the short-term resistance level of $42,800 that night, triggering automated buy orders. Technical indicators RSI and MACD both signaled bullish momentum, jointly driving the rally. The strengthening of global risk assets and a slight pullback in the US dollar index also supported the overall environment. Social media discussion volume surged, ETF topics gained high popularity, and short-term buying pressure further expanded, creating a “news + capital + sentiment” triple resonance.

Caution is advised regarding the current consensus-driven news outlook and the risk of short-term pullbacks due to chasing high prices. Future focus should be on the progress of Bitcoin ETF approval, large on-chain fund flows, the support and resistance levels of $42,800 and recent highs, and macro policy changes. Market volatility remains, so closely monitor market movements and real-time information.
