#比特币跌破8.1万美元 Bitcoin fell below $81,000, hitting an intraday low of around $80,800. It was down about 2–3% over 24 hours, giving back most of its September gains.

❓Why did it fall?

1️⃣Tighter macro liquidity: Brent crude briefly topped $104–105, 10-year Treasury yields surged to around 5.3%, and the US dollar strengthened—repricing non-yielding risk assets (BTC, gold, and growth stocks) all at once.

2️⃣A more hawkish Fed outlook: September’s meeting minutes hinted at another rate hike this year, prompting investors to proactively reduce exposure ahead of the 10/28 FOMC meeting.

3️⃣ETF flows reversed: US spot BTC ETFs saw about $485 million in net outflows in a single day—the largest since late June—removing a key source of buying support.

4️⃣Leveraged longs were flushed out: Total liquidations across the crypto market exceeded $1 billion over 24 hours, with more than $900 million from long positions. The $81,700–$83,300 range was a dense liquidation zone for longs; once prices broke below it, cascading liquidations intensified the sell-off.

5️⃣Spot trading volume was too thin: According to Glassnode, average daily spot and ETF trading volume was about $6.8 billion, below 90% of readings since January 2024. Existing capital alone couldn’t support the market. $BTC $ETH $SOL
