Bitcoin fell more than 2% to $77,161 after Iran launched ballistic missiles at American military installations following U.S. operations against two IRGC missile launch sites on Larak Island in the Strait of Hormuz. The cryptocurrency later recovered to about $77,813 after briefly rising above $79,000. Brent crude climbed above $90 a barrel, the 10-year Treasury yield reached 4.76%, and the dollar index strengthened to about 99.6, adding pressure to digital assets. Bitcoin futures open interest across CME, Binance and Hyperliquid rose despite the price decline, while 24-hour trading volume increased 50%. Analysts highlighted a potentially bearish divergence in Bitcoin's daily RSI (Relative Strength Index, a momentum gauge), with the reading at 70.7, and identified its $77,269 50-week exponential moving average as a key support level. U.S. spot Bitcoin ETFs recorded $217 million of net inflows on Aug. 31, led by BlackRock's IBIT at about $206 million. Polymarket data put the probability of Bitcoin reaching $85,000 before Dec. 31, 2026, at 68%.
