Bitcoin at US$ 81.4k: ETFs see largest daily outflow since June and Core accelerates bug fixes
₿ BITCOIN NOW — 23/10/2026 BTC: US$ 81,450 | 24h: approx. -3.4% | 24h High: US$ 84,796 | 24h Low: US$ 80,814 A day of pressure for Bitcoin: the price fell below US$ 81 thousand and stabilized near US$ 81.5 thousand, following the decline in technology stocks (Nasdaq -2.6%, worst session since June) and the rise in oil, which renewed inflation fears ahead of the Fed meeting on October 27 and 28. 📰 WHAT HAPPENED TODAY 1. Bitcoin ETFs see largest daily outflow since June. US spot ETFs recorded US$ 635.6 million in redemptions on Thursday, led by IBIT (US$ 254 mi) and FBTC (US$ 217 mi). For the week, the balance is still positive, at US$ 442.7 million. Why it matters: institutional flows have been sustaining the market, and the reversal signals caution amid the macro scenario.

A proposal by Antoine Poinsot, already approved by maintainers, provides for immediate correction and alerts for bugs easy to find again with LLMs, instead of embargoes that could last up to a year. Why it matters: shortens the window in which attackers can exploit known flaws in the software that sustains the network. Source: Bitcoin Magazine 3. Macro weighs: oil at five-month highs. Brent rose after Houthi attack on Saudi Arabia, and about US$ 440 million in leveraged crypto positions were liquidated in 24 hours, most of them in long positions. Why it matters: oil and high interest rates reduce risk appetite and directly affect BTC. Sources: CoinDesk / The Block 🔗 SOURCES: theblock.co, coindesk.com, bitcoinmagazine.com
