Bitcoin Dips Below $81K as Kospi Slides 5.5% and Liquidations Hit $813M

A Stock Market Sell-Off Spills Into Crypto

Crypto traders woke up to a sharp swing on Tuesday. Bitcoin slipped below $81,000 in early trading, then bounced back above $84,000 before settling just above $83,000, according to CoinDesk.

Ether had a rougher ride, falling as low as $2,400 at one point.

The trigger came from outside crypto. It came from Seoul, where South Korea’s main stock index, the Kospi, fell 5.5% in a single session.

Why South Korean Chip Stocks Are Falling

The Kospi is heavily weighted toward chipmakers, which took the biggest hit. Samsung Electronics fell 7% on Tuesday, while SK Hynix dropped 10%.

Two worries drove the selling. First, growing doubt about how much money is being poured into artificial intelligence. Broadcom’s chief executive described current AI investing as “casino-like,” a remark that unsettled a market built on the AI boom.

The second is competition. Reported memory-chip advances at China’s CXMT raised fears that established chipmakers could face a stronger rival.

The Kospi now sits about 38% below its June all-time high.

How $813 Million in Liquidations Happened

The most striking number of the day came from the derivatives market. Crypto liquidations jumped 284% to $813 million over 24 hours, CoinDesk reported.

For beginners, a liquidation is easier to understand than it sounds. Many traders borrow money to make bigger bets, which is called trading with leverage. A trader with 10x leverage can control $10,000 of Bitcoin with just $1,000 of their own money.

That works well when the price moves in their favour. But if the price moves roughly 10% against them, they lose their $1,000. At that point, the exchange automatically closes the position to protect the loan. That forced sale is a liquidation.

When many of these positions close at once, forced selling can push prices down further, triggering even more liquidations. That chain reaction is why crypto prices can drop very fast and then bounce just as quickly, as Bitcoin did on Tuesday.

Traders Rush to Protect Themselves

Trading activity surged during the swing. Futures volume rose 66% to $212 billion in 24 hours, up from $126 billion the day before.

At the same time, open interest, which measures the total value of futures bets still open, fell 1.58% to $143.4 billion. Falling open interest alongside heavy volume suggests traders closed positions rather than opened new ones.

The options market told a similar story. Put options, which pay out if prices fall, dominated Bitcoin’s most-traded contracts for a second day in a row. The most-traded Ether contract was a $2,500 put expiring on October 16. This activity suggests traders are buying protection against further drops rather than betting heavily on a crash.

Interestingly, implied volatility for Bitcoin and Ether stayed near its lowest levels of the year. That suggests options traders do not yet expect a prolonged period of wild price swings.

Altcoins Take a Bigger Hit

Smaller tokens fell harder than market leaders, a familiar pattern during sell-offs. Starknet (STRK) dropped more than 17% to $0.08, LayerZero (ZRO) lost 14% and NEAR fell 11%.

Not everything went red. Stacks (STX) climbed 11.4%, standing out as one of the few gainers on a weak day. Anyone tracking crypto market prices on Tuesday would have seen a sea of losses with only a handful of exceptions.

The slide also adds to the market’s cautious stretch. Last week, Bitcoin and Ether ETFs lost $986 million in October, their biggest outflow since June, suggesting big investors had already been pulling back.

All Eyes on Wednesday’s Inflation Report

The next test arrives quickly. The US Consumer Price Index report is due on Wednesday, and forecasts point to headline inflation of 3.6% year over year, up from 3.4% the month before. Core inflation, which strips out food and energy, is forecast at 2.5%.

Inflation matters for crypto because it shapes interest rate decisions. Higher-than-expected inflation could make rate cuts less likely, which has often weighed on risk assets like Bitcoin. A softer reading may ease some of that pressure.

Third-quarter earnings from JPMorgan, Goldman Sachs, and Citigroup were also scheduled for Tuesday, adding another potential source of market movement.

Crypto Is Now Tied to the AI Trade

The bigger lesson from Tuesday is how closely crypto now moves with traditional markets. A sell-off in South Korean chip stocks, sparked by doubts about AI spending, was enough to shake Bitcoin within hours.

That link cuts both ways. When tech stocks rally, crypto has often benefited from the same wave of risk appetite. When confidence in the AI story wobbles, crypto can feel the shock just as fast.

For now, Bitcoin’s quick rebound above $83,000 suggests buyers were still willing to step in. Whether that holds may depend less on crypto-specific news and more on inflation data, bank earnings and the mood around AI. Readers following the latest crypto news this week may find that the biggest moves are being decided outside crypto altogether.
