Bitcoin trades at $81,587 and ether at $2,397 as the US equity market opens, ten minutes after the Nasdaq Composite posted its steepest one-day fall since June. Crypto holders should watch whether that equity weakness spreads into digital assets during today's session.
What actually happened
Bitcoin trades at $81,587, up +0.06% over 24 hours, after ranging between $80,989 and $81,912. Volume over the period reached $25.22 billion and its market capitalisation is $1.64 trillion. Ether trades at $2,397, up +0.12%, with a range of $2,373 to $2,414, volume of $11.44 billion and a market capitalisation of $292.92 billion.
Overnight, the Nasdaq Composite fell 2.6% on Thursday, its worst day since June, after Meta dropped 7% on AI spending concerns, CoinDesk reported. US spot bitcoin ETFs lost $635 million (USD) on Thursday, following more than $1 billion (USD) of inflows earlier in the week, according to CoinDesk.
How we got here
Bitcoin's 90-day realized volatility sits near 38%, close to Nvidia's 37% and far above the euro-dollar pair's 4.6%, CoinDesk found, down from a 58% average since January 2020. Bitcoin's July 1 low of $57,850 (USD) arrived 125 days before the 3 November US midterms, a wider gap than the 71, 38 and 13 days before prior cycle bottoms in 2015, 2018 and 2022, per CoinDesk.
Why this matters for you
For holders, bitcoin now swings more like a large tech stock than a currency, so Nasdaq stress can move its price without any crypto-specific cause. Thursday's $635 million (USD) ETF outflow, after three days topping $1 billion (USD) in inflows, shows flows can reverse fast. For builders on crypto rails, including AR and Web3 hardware, calmer realized volatility helps, but the equity link shows crypto markets remain exposed heading into next week's Fed decision.
The bigger question
Bitcoin's volatility has converged with Nvidia's near 37 to 38%, and its ETF flows reversed within a single day of a Nasdaq selloff. If that pattern holds, does bitcoin still function as a portfolio diversifier separate from equities, or has it become another high-beta technology asset that simply moves with Wall Street during periods of stress, regardless of its own underlying fundamentals?
What to watch
The Fed meets 27-28 October, a key signal for risk assets. US midterms fall on 3 November, a date historically tied to past bitcoin cycle bottoms, though this year's low came months earlier. Watch whether ETF flows stabilize and whether Nasdaq volatility spills further into crypto this week.
