On September 28, 2026, Bitcoin was trading between US$84,200 and US$84,550, showing modest gains of 0.2% to 0.5%. After a sharp rally last week, Bitcoin rebounded from near US$75,000 lows to US$76,000, briefly reaching an eight-month high of US$87,000 on September 21. Over the past week, Bitcoin has climbed 4% and more than 40% for Q3.
This rise is driven by heavy ETF buying, with US spot Bitcoin ETFs inflowing about US$2.4 to US$3 billion, including nearly US$1 billion on September 21 alone. Institutional demand, such as from Strategy, also played a role, despite the Fed's first rate hike and Senate's failure to advance the CLARITY Act. Technical and seasonal factors, like closing above the 50-week moving average, indicate a strong third quarter for Bitcoin.
However, Bitcoin dominance remains at 58.5%, below the 55% threshold that would typically signal the start of an altcoin season. The Altcoin Season Index, measuring the percentage of top 50 coins outperforming Bitcoin over 90 days, is between 57 and 70, indicating a transitional phase rather than a full altseason. While some altcoins like ZEC, UNI, and mid-cap coins are outperforming BTC, the broader market has not shifted.
Analysts suggest this is a Bitcoin-led move, with ETF flows currently pulling capital into Bitcoin. For investors, buying Bitcoin now offers exposure to ETF flows and institutional demand, while buying alts carries higher risk if dominance remains high. A selective approach focusing on names showing 90-day outperformance versus BTC, along with monitoring ETH/BTC, the Altcoin Season Index, and Bitcoin dominance, is advised.
