BTC and ETH liquidity rebuilt a year after 10/10, but altcoin depth keeps thinning
BTC 1% depth hit about $11.7M on Oct. 7, while weekly CEX spot volume averaged ~$279B versus $801B in the crash week.
One year after the Oct. 10, 2025 liquidation shock that wiped out more than $19 billion in leveraged positions, order-book liquidity has rebuilt unevenly across crypto. Bitcoin and ether books are deeper in dollar terms on major centralized exchanges, while altcoin dollar depth and spot volumes remain structurally weaker.
Key Takeaways
- More than $19 billion in leveraged positions were liquidated on Oct. 10, 2025, after a fast drop in thin Friday evening (U.S. time) trading.
- Bitcoin depth within 1% of price reached about $11.7 million on Oct. 7, 2026, up from about $9 million at the start of 2026 and about $6.9 million at the start of 2025.
- Ether depth tightened materially versus crash day, with about $4.2 million sitting within 0.5% of price and roughly $5.3 million within 1%.
- Altcoin dollar depth has stepped down at every snapshot since Jan. 1, 2025, alongside weekly CEX spot volume averaging about $279 billion versus $801 billion in the crash week.
A One-Year Liquidity Split After the 10/10 Liquidation Shock
The clean headline from the 10/10/2025 event was the liquidation print. More than $19 billion in leveraged positions got forced out in a single day, described as the largest one-day liquidation event in crypto history.
The more durable takeaway is what happened to the market’s plumbing after the panic cleared. Market depth snapshots across major centralized exchanges show BTC and ETH rebuilt resting liquidity near the price to levels above both crash day and early-2025 baselines. Altcoins did not.
That split matters because it changes where execution risk lives. In majors, the book can take more size before price impact becomes the trade. Outside majors, thinner dollar depth and lower spot activity increase slippage risk, especially when volatility picks up.
The flash-crash setup is worth remembering because it explains why liquidity vanished so quickly. After days earlier trading above $126,000, bitcoin was around $122,600 on the morning of Oct. 10, 2025, then fell below $105,000 within hours, with much of the decline happening in minutes during thin Friday evening (U.S. time) trading after President Donald Trump announced 100% tariffs on Chinese imports.
The Depth Snapshots: Where BTC and ETH Rebuilt
The comparison is built on four points in time: Jan. 1, 2025. Oct. 10, 2025. Jan. 1, 2026. And “this week,” using market depth across major centralized exchanges.
Depth here means the dollar value of buy and sell limit orders resting near the current price. The bands matter. “Within 0.5%” and “within 1%” are the tight zones where most real execution happens for active traders. “At 5%” is farther out, where liquidity is more conditional and often disappears first when the market gaps.
Bitcoin’s near-price book is the clearest rebuild. About $11.7 million sat within 1% of BTC’s price on Oct. 7, 2026. That was roughly 75% more than on crash day a year earlier. The same 1% depth was about $9 million at the start of 2026 and about $6.9 million at the start of 2025.
The shape of the recovery matters as much as the headline number. Most of BTC’s improvement is concentrated close to the price, where market makers quote most actively. Further out, at 5% from price, BTC depth was around $24 million on Oct. 7, 2026, roughly where it was in January 2025.
Ether’s recovery is tighter-band heavy. Depth within 0.5% of ETH’s price more than doubled since crash day to about $4.2 million. At 1%, it rose by about three-quarters to roughly $5.3 million, above both January readings.
Why ‘Deeper in Dollars’ Isn’t Just a Price Artifact
Dollar depth can lie when price levels change. If an asset doubles, the same number of coins posted on the book looks “deeper” in dollars without any new risk capital showing up.
That is not the story here for BTC. Bitcoin is described as about one-third cheaper than before the crash, yet the book is deeper in dollar terms near the price. Mechanically, that points to more market-maker capital being posted, not just a higher nominal price inflating the metric.
Saksham Diwan framed it bluntly: “The majors’ deepening is real capital, not a price effect,” referring to BTC and ETH order-book improvements.
What stands out is where the capital is willing to sit. BTC’s 1% depth expanded meaningfully, while 5% depth is roughly unchanged versus early 2025. That is consistent with market makers tightening up around the touch, but not necessarily warehousing more tail risk further out on the curve.
This is the part traders tend to skip. A deeper tight band improves day-to-day execution. It does not guarantee protection in a gap, because the 5% zone is where the book has to be real when the market is moving too fast for passive quoting.
Altcoin Liquidity Keeps Eroding as CEX Spot Volumes Stay Depressed
Altcoins are the other side of the ledger. In the measured basket, altcoin dollar depth was greatest on Jan. 1, 2025, and lower on each subsequent snapshot.
The declines are visible both near and away from the price. At 5% from price, altcoin depth is down about a third since the start of 2025 to around $2 million. At 1%, it has fallen by about a sixth over the same period.
There is a catch in the optics. Measured in tokens rather than dollars, alt depth looks healthier. Token-unit depth peaked on Jan. 1, 2026 and has eased only modestly since. The interpretation offered is that falling token prices can make token-unit depth look stable even as the actual capital committed to the book erodes.
Spot activity lines up with that story. Weekly spot volume on centralized exchanges averaged around $279 billion over the four weeks to Sept. 27, 2026, nearly two-thirds below the $801 billion traded in the crash week. Volume bottomed around $135 billion in August 2026 and has roughly doubled since, but it remains well short of the levels seen around the crash.
The unresolved piece for execution planning is mapping. The data references “major centralized exchanges” and an “altcoin basket,” but does not specify which venues and which tokens are included. Without that, traders cannot cleanly separate a broad altcoin liquidity problem from a concentration problem where a few large-cap alts carry the book and the rest are effectively thin.
Stress-Test Signals From This Week’s Selloff
The rebuilt books did not get a full 10/10-style shock test, but they did get a live-fire drill. During the Oct. 7–8, 2026 selloff, bitcoin’s 1% depth fell about 12% between Oct. 7 and Oct. 8.
That is the practical link between “depth” as a chart and depth as fill quality. When the market leans, the first thing that happens is liquidity steps back, even in majors. The question is whether it steps back temporarily and refills, or whether it keeps deteriorating as volatility persists.
Ether’s response was different in a way traders should care about. ETH’s tightest band thinned slightly during the selloff, while orders further from the price increased. That is a subtle shift in where liquidity is willing to sit. It can mean market makers are widening out, posting size at safer distances, and letting the near-touch get thinner.
This is why the BTC and ETH rebuild should be read as “more tradable than a year ago,” not “immune.” Liquidity is a behavior, not a constant. The stress test is whether the behavior holds when the market is moving fast.
Signals to Watch for BTC/ETH liquidity rebuild vs altcoin erosion
BTC’s near-price depth is the first tell. The immediate question is whether the roughly 12% drop in BTC 1% depth from Oct. 7 to Oct. 8 stabilizes, or whether it continues to deteriorate as volatility persists.
Spot volume is the second tell because it funds the ecosystem’s risk appetite. Weekly CEX spot volume averaged about $279 billion over the four weeks to Sept. 27, 2026. Follow-through toward prior-cycle highs would support broader liquidity provision. A rollover back toward the roughly $135 billion August 2026 low would argue the opposite.
Altcoin depth at the 1% and 5% bands is the third tell. The cited level around $2 million at 5% and the roughly one-sixth decline at 1% since early 2025 are the numbers that would need to stop bleeding to make “alt liquidity recovery” more than a narrative.
The final signal is methodological clarity. More detail from data providers on which venues make up the “major centralized exchanges” sample and which tokens comprise the “altcoin basket” is what allows traders to translate a macro liquidity read into specific execution assumptions.
My Read: Majors Look More Tradable, but Alt Execution Risk Is Still the Trade
The number that matters is not the $19 billion liquidation print. It is what the market did with risk capital afterward. BTC at about $11.7 million within 1% on Oct. 7, 2026 and ETH at about $4.2 million within 0.5% are consistent with market makers running larger, tighter books in the two names that clear the most flow.
The “not a price effect” point is the hinge. BTC being about one-third cheaper than before the crash, yet showing higher dollar depth near the price, is hard to explain without real balance sheet returning to the touch. That is constructive for execution in majors, but it also implies the other side of the trade. Capital is choosing where to sit.
If weekly CEX spot volume keeps climbing from the ~$279 billion average toward prior-cycle highs, the base case shifts toward broadening liquidity, including selective alts. If volume rolls back toward the ~$135 billion August low, the divergence likely hardens, because thin activity makes it rational to quote tight in BTC/ETH and ration risk everywhere else.
The threshold that matters is whether BTC 1% depth stabilizes after the Oct. 7–8 drawdown and refills on the next volatility pulse. If it does, the rebuild is structural. If it keeps stepping down while altcoin dollar depth continues to erode, the core thesis holds: majors are tradable again, but execution risk remains concentrated in alts where the book is still shrinking in dollars.
