Bitcoin retreated to around $81,400 on Tuesday, sliding 0.5% since midnight UTC despite U.S. spot exchange-traded funds attracting $526.6 million in net inflows the prior day, marking their largest single-day tally in nearly a month [1]. At the time of writing, $BTC traded at $81,454, down 0.9% over the past 24 hours. Weakness across Asian equity markets filtered into digital assets as South Korea's Kospi dropped 3.73% to its lowest level since April 7, led lower by semiconductor heavyweights SK Hynix and Samsung Electronics following renewed concerns over artificial intelligence capital expenditures [1]. Derivatives markets reflected defensive positioning alongside the macro softness [1]. On Deribit, put options outpaced calls by more than two to one over 24 hours, with the Oct. 30 $80,000 strike put recording the heaviest trading volume [1]. Out-of-the-money puts commanded a premium of 2.5 to 4 volatility points over equivalent calls across expiries [1]. Total crypto liquidations reached $155.1 million across 24 hours, down 54.7% from the previous day, with long positions accounting for approximately 69% of the wiped positions [1]. Aggregated open interest across Bitcoin contracts stood at $27.4 billion on Coinalyze [1]. ## Altcoins Track Equities Lower Major altcoins mirrored the pullback, with $ETH slipping 0.9% to near $2,385 and decentralized finance benchmarks leading declines [1]. Layer-2 assets experienced steeper losses: Arbitrum's $ARB fell 3.6% and Starknet's $STRK dropped 3.2% [1]. DeFi protocols also surrendered recent momentum, as Uniswap's $UNI dropped 2.3% to roughly $7.14, extending its monthly drawdown to approximately 20% despite generating a record $14.81 million in September protocol revenue under its fee mechanism [1]. Bucking the downtrend, Celestia's $TIA gained 2.2% to around $0.63 [1]. The token remains up roughly 42% over the past month, buoyed by recent benchmarks showing its Fibre scaling system processing 3.07 terabits per second alongside its integration by options exchange Derive [1]. The broader digital asset market faces external headwinds from elevated crude oil, with Brent hovering near $110 per barrel amid geopolitical tensions, alongside an active U.S. corporate earnings calendar that includes approximately 70 S&P 500 reports scheduled throughout the week [1]. ## Sources 1.
