One Year After the $19 Billion Crypto Liquidation, Bitcoin and Ether Order Books Are Deeper While Altcoins Lag

On the morning of Oct. 10, 2025, Bitcoin sat at $122,600, days after a record high above $126,000. A few hours later it was below $105,000.

The trigger was a Friday-evening announcement by President Donald Trump of 100% tariffs on Chinese imports, along with a threat of new export controls. Much of the drop came within minutes, in thin U.S. evening trading.

According to CoinGlass data, about $19.1 billion in positions were liquidated between Oct. 10 and 11. Most were longs, meaning traders who had borrowed to bet on higher prices. Total crypto market capitalization fell more than 9% at one point, to around $3.8 trillion.

How the cascade worked

Leverage did the damage. A trader using 10x leverage controls a $10,000 position with $1,000 of margin, and a 10% move against him wipes that margin out.

When prices fell, exchanges automatically closed those positions. The forced selling pushed prices lower and triggered the next round. Spreads widened and buyers thinned out. Major exchanges saw severe price dislocations during the chaos.

The account BullTheory posted on X put the toll at over 1.6 million affected traders and roughly $800 billion in market value erased within hours. Those are that account's estimates.

Majors rebuilt, with a caveat

CoinDesk Research compared order book depth across major centralized exchanges on four dates: Jan. 1, 2025, Oct. 10, 2025, Jan. 1, 2026, and this week. Depth measures the buy and sell orders resting near the current price. A deeper book lets a large trade go through without moving the market.

On Oct. 7, about $11.7 million sat within 1% of Bitcoin's price. That is roughly 75% more than on crash day. It compares with about $9 million at the start of this year and about $6.9 million at the start of 2025.

Bitcoin is about one-third cheaper than before the crash, so the dollar figure is not a price effect. CoinDesk Researcher Saksham Diwan said, "The majors' deepening is real capital, not a price effect."

The gains are concentrated near the price. At 5% away, Bitcoin depth of around $24 million is roughly where it stood in January 2025.

Ether's recovery is stronger by some measures. Depth within 0.5% of the price has more than doubled since crash day, to about $4.2 million. At 1%, it is up about three-quarters, to roughly $5.3 million, above both January readings.

Smaller tokens and spot trading have not followed, according to CoinDesk Research.

Altcoins still carry the damage

Open interest in altcoin futures, the total value of outstanding contracts, fell from about $70 billion before the crash to around $30 billion by mid-December 2025. Perpetual futures open interest across the market also contracted sharply.

Altcoin rallies have also shortened. The median rally lasted 60 days in 2024. In 2025 it lasted roughly 19 to 20 days, according to Crypto Briefing.

Crypto Briefing's Vivian Nguyen argues that the market now runs at two speeds. Bitcoin and Ether behave more like institutional assets, backed by ETF demand and steadier order books. Everything else trades more like a high-beta side bet.

There is a counterpoint inside the same data. Nguyen notes that less altcoin leverage means fewer forced sellers if prices drop sharply again. It also means less fuel for sustained rallies, because leveraged buyers amplify upside moves too.

Where prices stand

Bitcoin traded between $80,000 and $87,000 in early October 2026, well below the roughly $126,000 peak. U.S. spot Bitcoin ETFs have seen renewed demand. In October the products took in $102.7 million in a single day.

That is the institutional bid CoinDesk and Crypto Briefing both credit for the rebuilt majors.

The first test

The new books were tested this week. As the market sold off, Bitcoin's 1% depth fell about 12% between Oct. 7 and Oct. 8. Ether's tightest band thinned slightly, though orders farther from the price increased.

That is a small move next to the crash-day collapse. It still shows that depth can leave quickly when prices drop.

Whether exchanges have tightened liquidation engines, margin rules or insurance-fund practices since the crash is not established in the data above. Coin Edition says the crash exposed weaknesses in exchange risk controls. None of the sources identifies a specific industry-wide fix.

It is an open question whether the roughly $11.7 million within 1% of Bitcoin's price holds up in the next sharp selloff. This week's 12% dip is the data point to watch.
