Good Morning Blocksignal Community,
Thursday took back what Wednesday had given. Bitcoin opened near 84,000 dollars, its highest level since early October, and slid to roughly 81,300 by the evening, a drop of about 3 percent. Three themes shaped the day. Oil climbed back above 111 dollars after fresh attacks in the Gulf region and pulled equities down with it, the sell-off hit altcoins harder than Bitcoin and pushed Bitcoin dominance to a five-month high, and US spot Bitcoin ETFs were still digesting their strongest inflow day in nearly a month as the Fed decision on October 28 comes into view.
Market action and drivers
Bitcoin traded as high as 84,500 on Wednesday before reversing on Thursday morning and briefly slipping below 81,000 in the evening. Ether fell about 3.6 percent to roughly 2,380 after trading above 2,500, Solana dropped about 3.3 percent to near 103, and XRP gave back 6.4 percent to 1.30. Zcash, which had been the standout of the week, lost about 10 percent. The cause was not crypto-specific. Brent crude rose roughly 3 percent to above 111 dollars, near its highest since May, after Houthi strikes on a Saudi airport and oil field, and the higher energy price revived inflation worries that weigh on every risk asset. Crypto simply moved with equities. Over the past weeks that correlation has become the main driver, and yesterday it ran to the downside.
Derivatives and on-chain
Bitcoin dominance touched 60 percent on Wednesday, the highest since May, and stayed close to it. That reading fits the pattern of the day: capital retreats into Bitcoin first when risk appetite fades, while smaller tokens carry the losses. The CoinDesk memecoin index fell more than 5 percent and the DeFi index about 2.5 percent. Open interest across major exchanges eased 2.2 percent to 37.8 billion dollars, roughly in line with price, so this was a repricing rather than a leverage flush. Traders were caught on both sides as the breakout reversed, with shorts squeezed on the way up and longs forced out on the way down. On Deribit, call open interest stands at about 1.7 times put open interest, which shows that the options market still leans bullish despite the pullback. Glassnode noted that buyers stepped in near ETF and treasury cost bases when Bitcoin touched 80,000 on October 15, and it sees the next dense zone of sell orders between 85,000 and 87,500.
Macro and geopolitics
The equity picture was clearly worse than the crypto one. The Nasdaq fell about 2.6 percent in US trading, the S&P 500 lost roughly 1.2 percent, and Meta dropped about 7 percent while Nvidia and Amazon each gave up more than 4 percent as doubts about AI returns returned. Asia set the tone overnight: South Korea's Kospi fell 3.5 percent, Japan's Nikkei 2.65 percent, and China's CSI 300 slipped into a bear market, 20 percent below its June peak. The yen rallied as investors looked for safe havens. US jobless claims came in at 194,000, below forecasts, which keeps the labor market in the picture for the Fed, but the oil price dominated the reaction.
Adoption and industry
Spot Bitcoin ETFs took in 528 million dollars on Wednesday, the largest single-day inflow in almost a month, led by BlackRock's IBIT with 235 million and Fidelity's FBTC with 213 million. That brought the three-day total above 1 billion dollars. Ether ETFs added 14.9 million dollars and ended a five-day outflow streak. CoinDesk put the inflows into perspective: since July the funds have averaged about 86 million dollars a day, while earlier steep rallies were backed by far larger and more regular inflows, so the recent numbers are encouraging but not yet a confirmation. On the network side, Solana's Alpenglow upgrade went live on October 21, but the token fell with the market regardless, and Ethereum developers outlined a draft change that could cut finality time to about four minutes.
Regulation
There was little movement in Washington. The CLARITY Act market structure bill has stalled since the failed Senate vote on September 15, with no new action this week, so the regulatory calendar offers no near-term catalyst.
Narratives and positioning
The narrative has shifted back from crypto-specific optimism to a macro-first reading. LMAX analyst Joel Kruger described crypto's earlier outperformance as having given way to closer alignment with equities, and Bitcoin's 28-day realized volatility near its 2026 low suggests that the market is coiled and waiting for a trigger. The long-to-short ratio on OKX rose to 1.95 from 1.21 a day earlier, which means positioning leaned long going into the drop.
Today's Watch
Friday brings US business surveys, and the larger events sit just behind it: the Fed decision on October 28 and the US midterm elections on November 3. For Bitcoin, the 80,000 dollar area is the level that buyers defended on October 15, and a move back toward 84,000 would bring the 85,000 to 87,500 sell zone into play. Ether has its near-term support around 2,300 and Solana around 100. Oil remains the swing factor, because another jump above 112 dollars would likely keep pressure on equities and crypto alike. As always, this is market commentary, not investment advice.
