Bitcoin Slips to $81,400 Despite Strongest ETF Inflow in Nearly a Month
Bitcoin slipped to around $81,400 on Tuesday, down 0.5% since midnight UTC, in a session defined by a striking divergence: the largest daily inflow into U.S. spot bitcoin ETFs in nearly a month failed to lift the world’s largest cryptocurrency, as weakness in Asian semiconductor stocks set a risk-off tone across global markets.
U.S. spot bitcoin exchange-traded funds attracted $526.6 million on Monday, their biggest single-day haul in almost four weeks. Ordinarily, an inflow of that magnitude would be read as a bullish signal, evidence that institutional allocators are using the dip to add exposure. Instead, bitcoin traded near $81,462 at the time of writing, with the price action dictated less by crypto-native flows than by macro currents flowing out of Asia’s technology sector.
The immediate catalyst came from Seoul. South Korea’s benchmark Kospi index fell 3.73% to its lowest close since April 7, dragged lower by heavyweights SK Hynix and Samsung Electronics as renewed worries over AI spending weighed on chipmakers’ shares. The sell-off spilled into U.S. equity futures, with Nasdaq 100 futures down 0.31%, and from there into digital assets.
The episode is a reminder that bitcoin, whatever its long-term diversification thesis, still trades as a high-beta risk asset on days when the technology complex wobbles. For more on how the largest cryptocurrency responds to equity market stress, see our Bitcoin coverage.
Options Traders Lean Bearish as Puts Outnumber Calls
The most telling signal of the session came from the derivatives market. On Deribit, the dominant venue for bitcoin options, puts outtraded calls by more than two to one over the 24-hour period. The busiest contract was the October 30 $80,000 put, a strike that sits below the current spot price and would only pay out if bitcoin breaks lower in the next fortnight.
The pricing structure tells the same story. Out-of-the-money puts cost more than equivalent calls by 2.5 to 4 volatility points across expiries, a bearish skew that shows traders are willing to pay a premium for protection against a drawdown. Skew of this kind tends to widen when market participants fear a sharp move lower but do not necessarily want to sell spot outright.
There is a nuance worth noting. Open interest still leans toward calls at the $90,000 to $100,000 strikes for October 30, meaning a cohort of traders is positioned for upside into the end of the month. The market is therefore split between two camps: leveraged bulls holding cheap upside calls, and a defensive cohort buying near-dated puts as insurance. That combination, heavy call open interest above the market and heavy put volume below it, often precedes elevated volatility in either direction.
Futures positioning adds further texture. Bitcoin open interest on Coinalyze fell to $27.4 billion, down 0.6% over 24 hours, while the aggregated funding rate stood at roughly 8.8% annualised. Longs hold around 55% of bitcoin positions, with a long/short ratio of 1.24. Binance’s top traders show a similar tilt, with a BTC-USDT position ratio of 1.78 on CoinGlass. Ether’s funding of about 3.9% annualised suggests a comparatively more measured bullish bias among traders in the second-largest cryptocurrency.
Liquidations were contained relative to the previous day. CoinGlass recorded $155.1 million of liquidations over 24 hours, down 54.7% from the prior period, with longs accounting for about 69% of the total on CoinMarketCap’s tally. Bitcoin and ether each saw roughly $30 million in liquidations on Coinalyze, together about half of the $120.6 million that platform tracked.
Altcoins Give Back Monday’s Gains as DeFi Lags
Altcoin losses were broadly in line with bitcoin, with a few notable exceptions. Ether fell 0.9% to near $2,385, while the CoinDesk 80 (CD80) lost 0.34%, compared with a 0.33% drop for the bitcoin-heavy CoinDesk 5 (CD5).
The decentralised finance sector gave back Monday’s lead and was the weakest of the CoinDesk benchmarks, with the sector index (DFX) dropping 1.2%. Uniswap’s UNI lost 2.3% to about $7.14 and Morpho fell 2.5%. UNI has slumped about 20% over the month even though its fee switch lifted protocol revenue to $14.81 million in September, its strongest month since it began retaining fees, according to Token Terminal. The disconnect between improving protocol fundamentals and a falling token price suggests the market is treating DeFi exposure as a proxy for broader risk appetite rather than valuing it on its own metrics.
Ethena’s ENA fell 1.9%, extending a decline of about 30% over the month from a late-September peak near 29 cents. The protocol’s USDe supply of about $4.7 billion, down from a peak near $15 billion, remains well short of the $7.5 billion level at which ENA buybacks would switch on, removing a potential source of token support.
Layer-2 tokens were among the weakest performers. Arbitrum’s ARB fell 3.6% and Starknet’s STRK dropped 3.2%. Starknet remains up about 29% over the month after surging on October 9 and 10, when the network said it was considering becoming a standalone quantum-resistant layer-1 by 2027.
The standout gainer was Celestia, which rose 2.2% to around 63 cents, the biggest advance on the CoinDesk 100 Index, adding to a gain of about 42% over the month. The run has coincided with Celestia’s October 1 benchmark showing its Fibre scaling system averaging 3.07 terabits per second, and with options exchange Derive choosing Celestia for data availability in its V3 release. The next test comes on October 31, when an unlock of 5.58 million TIA is scheduled, according to Tokenomist.
At the other end, The Sandbox led the CoinDesk 100 lower with a 4.5% drop to about 6 cents, giving back part of a gain of about 30% over the month. That rally began after South Korean exchanges Upbit, Bithumb and Coinone lifted trading cautions imposed in August following a bridge exploit.
Macro Backdrop: Oil, Earnings and the AI Question
Beyond the chip sell-off, the macro environment offers plenty for crypto traders to digest. Brent crude is near $110 a barrel as Houthi attacks on Saudi Arabia keep supply risks in view, sustaining inflationary pressure that complicates the outlook for monetary policy. Elevated energy prices feed through to headline inflation, which in turn shapes expectations for interest rate cuts, a variable that has historically moved bitcoin and other risk assets.
The earnings calendar is equally loaded. Roughly 70 S&P 500 companies report this week, with General Motors before the bell and United Airlines after the close. Corporate results will help determine whether the AI spending worries that hammered SK Hynix and Samsung Electronics are justified, or whether the Kospi sell-off proves an overreaction. If U.S. technology earnings disappoint, the same risk-off impulse that dragged bitcoin lower on Tuesday could intensify.
The regulatory backdrop remains active on multiple fronts. France’s parliament has approved a vote to hit stablecoin trades with a 31% capital gains tax, a move that would raise the cost of trading dollar-pegged assets for French investors if enacted. Kazakhstan’s courts have barred Coinbase and five other firms from offering unlicensed crypto services in the Astana International Financial Centre. Microsoft, Alphabet and Goldman Sachs have joined objections to OKX’s tokenized stock trading plans with Intercontinental Exchange. And BlackRock has moved to shield bitcoin investors from losses after a rival fund weathered a 50% crash, a sign that asset managers are competing on downside protections as much as on fees.
The Analyst’s View
The tension in this market is between flows and positioning. Monday’s $526.6 million ETF inflow is genuine institutional demand, the kind that has historically marked accumulation phases. Yet the options market is paying a premium for protection, put volume is running at more than double call volume, and the busiest contract targets $80,000 by month-end. When spot demand and derivatives sentiment diverge this sharply, the market is effectively voting on whether the AI-driven equity wobble is a passing scare or the start of a broader de-risking.
The $80,000 level, where the most actively traded October 30 put sits, is the near-term line in the sand. A hold above it, particularly if this week’s earnings season calms the AI spending fears, would leave the call open interest at $90,000 to $100,000 looking prescient rather than speculative. A break below, with Brent near $110 and funding rates still positive at 8.8% annualised, could force leveraged longs, who hold 55% of positions, to unwind into weakness. The next 48 hours of corporate earnings may decide which scenario plays out.
