A year after the crypto market's historic Oct. 10, 2025 crash, order-book liquidity in Bitcoin and Ether has substantially recovered, according to research cited by BitcoinKE. The rebound, however, has been uneven: smaller tokens continue to trade with thinner order books and remain more exposed to market volatility.

The Oct. 10, 2025 sell-off stands as the largest single-day liquidation event in crypto market history. As BitcoinKE reported at the time, the crash forced a rapid unwind ofaged positions across derivatives venues, with an estimated $19 billion in positions liquidated within 24 hours after an abrupt escalation in U.S.-China trade tensions sent risk assets tumbling.

Since then, depth in the two largest crypto assets has rebuilt significantly. Bitcoin's order-book depth within 1% of its market price rose about 75% year-on-year to $11.7 million, while Ether's depth within 0.5% of its market price more than doubled to $4.2 million. Order-book depth measures the cumulative value of buy and sell orders resting close to the prevailing price and is a standard gauge of how easily large trades can be executed without significant slippage. The mechanics cut both ways: with fewer resting orders, even moderately sized trades can move the price, while deeper books cushion larger flows.

Bitcoin trades at roughly one-third of its pre-crash price, but a deeper book reflects more capital committed by market makers. Ether's liquidity recovery is stronger still.

Depth and trading volume capture different sides of market health — one counts orders resting on the books at a given moment, the other trades actually executed — and by the second measure, activity has yet to return to the levels seen during the turmoil. Weekly spot trading volume on centralized exchanges averaged $279 billion in the four weeks to September 27, 2026, down nearly 65% from $801 billion during the crash week, when the sell-off drove a surge in turnover — meaning the decline is measured against crisis-elevated activity rather than ordinary conditions.

Taken together, the figures point to a two-tier recovery. Liquidity has strengthened in the two largest cryptocurrencies, while thinner order books and weaker trading activity leave altcoins more vulnerable to sharp price swings. Whether altcoin order books rebuild and spot turnover rebounds is the measure to watch for how broad the recovery ultimately proves.

The findings follow BitcoinKE's analysis of how Bitcoin's flash drop put Hyperliquid's growing influence on price discovery in focus.
