Bitcoin and Ether in deep liquidity channels while smaller tokens sit in shallow channels

Bitcoin and Ether Rebuilt Their Liquidity After 10/10—Altcoins Did Not

One year after crypto’s brutal 10/10 flash crash, the market has rebuilt—but not evenly.

Bitcoin and Ether now have deeper order books than they did before the October 2025 wipeout. Smaller tokens are telling a very different story.

Their liquidity has continued to thin, leaving traders with more slippage and less protection when the next wave of forced selling arrives.

That split matters because liquidity is the market’s shock absorber. A deep order book can take a large buy or sell without moving the price too far.

A thin one can turn an ordinary exit into a waterfall.

CoinDesk Research compared centralized-exchange market depth on four dates: the start of 2025, the October 10 crash, the start of 2026 and this week. Its findings show that about $11.7 million in Bitcoin orders sat within 1% of the market price on October 7.

That was roughly 75% deeper than the crash-day book and well above the approximately $6.9 million measured at the beginning of 2025.

Bitcoin was trading roughly one-third below its 2025 peak. The extra depth measured in dollars therefore reflected more capital committed by market makers near the price.

Ether’s near-market book showed an even sharper recovery. Depth within 0.5% of the price had more than doubled from crash day to about $4.2 million, while depth within 1% climbed to roughly $5.3 million.

Deeper books have not made Bitcoin tame. A current on-chain snapshot shows how aggressively leveraged traders positioned just before another recent move below $84,000:

The recovery fades quickly outside the two market leaders. CoinDesk found that altcoin depth measured in dollars has been sliding since early 2025.

Falling token prices can make percentage-based depth look less alarming than it is. The dollar figures show less real capital available to absorb trades.

Spot activity is also subdued. Weekly marketwide spot volume is still nearly two-thirds below the crash-week peak, even after roughly doubling from an August low.

That leaves smaller assets exposed to violent gaps whenever leverage unwinds or a macro shock drives traders toward the exits at once.

The European Securities and Markets Authority’s 2026 risk review described the 10/10 event as a collision of leverage, thin markets and platform-specific dislocations. Bitcoin and Ether fell hard.

XRP, Cardano, Dogecoin and other major altcoins suffered much steeper intraday drops as more than $19 billion in leveraged positions were liquidated.

ESMA counted roughly 1.6 million affected traders and highlighted a second layer of damage inside exchange markets. On Binance, USDe fell near $0.65 while wrapped Ether and Solana products broke sharply from the assets they were supposed to track.

Those dislocations showed what happens when liquidations strike fragmented venues at the same time. Thin collateral markets can become part of the crash instead of absorbing it.

Deeper books make Bitcoin and Ether more resilient. They cannot guarantee higher prices.

Market makers can pull quotes, futures leverage can overwhelm spot buyers, and institutional demand can fade just when traders expect it to accelerate.

CryptoQuant’s current read captures that tension: spot demand is recovering, but U.S. demand has not yet supplied a clean confirmation.

Crypto’s biggest assets have rebuilt meaningful defenses since the worst liquidation day in the market’s history. Much of the altcoin market remains thin.

The next stress test may hit the entire board. The damage is unlikely to be distributed evenly.
