Bitcoin and Ether Liquidity Rebound a Year After the 10/10 Crash, Altcoins Still Struggle
One year after the 10/10 flash crash, Bitcoin and Ether order books are deeper, but altcoin liquidity stays low, signaling a split recovery.
According to CoinDesk: Bitcoin, Ethereum, Crypto News and Price Data, the market’s plumbing looks very different a year after the October 10, 2025 flash crash. Bitcoin and Ether order books now hold more resting liquidity than they did on crash day, while most altcoins and spot‑trade volumes remain well below historic levels.
What happened
On the morning of Oct. 10, 2025, Bitcoin hovered just above $126,000 before tumbling to under $105,000 in minutes after President Donald Trump announced 100 % tariffs on Chinese imports. The rapid decline wiped out more than $19 billion in leveraged positions in a single day – the largest liquidation event in crypto history.
CoinDesk Research measured market depth – the total value of buy and sell orders waiting near the current price – on four dates: Jan. 1 2025, Oct. 10 2025 (the crash), Jan. 1 2026 and the week of Oct. 7 2026. Depth tells us how much volume a large trade can absorb without moving the market; a deeper book means a single big order is less likely to cause a price swing.
Bitcoin’s 1 % band now contains about $11.7 million, roughly 75 % more than on the crash day and double the amount seen at the start of 2025. Ether’s tightest band (within 0.5 % of price) has more than doubled to $4.2 million, with the 1 % band up about 75 % to $5.3 million. Both figures exceed the levels recorded in January 2025.
Altcoins tell a different story. In the same basket of non‑major tokens, dollar‑denominated depth at 5 % from price has fallen by a third since early 2025, and depth at 1 % is down about a sixth. When measured in token units the numbers look healthier, but that reflects lower prices rather than real capital returning. Spot‑trade volume on centralized exchanges averages $279 billion per week – only a third of the $801 billion seen during the crash week – and, although it has doubled since its August low, it remains far from pre‑crash levels.
Why it works that way
Liquidity in crypto markets is supplied mainly by market makers – firms that post buy and sell orders to capture the spread between the bid and ask. When a market is thin, a single large order can sweep through the order book, forcing the price to move sharply. The 10/10 crash proved how fragile that system can be: leveraged traders were forced to unwind positions, and the resulting cascade erased billions of dollars of open orders.
After the crash, market makers reassessed where to place capital. Bitcoin and Ether are the two assets with the deepest institutional demand, the most reliable price feeds, and the highest trading volume on major exchanges. By concentrating capital around these majors, market makers can earn tighter spreads and lower risk of inventory loss. The deeper books we see now are therefore a product of “capital rotation”: funds that were once spread across dozens of tokens have migrated to the assets that promise the most reliable returns.
The mechanics of depth measurement also matter. The reports quote dollar‑value depth, not token count. Because Bitcoin’s price is now about one‑third lower than it was before the crash, the same dollar amount represents more coins, meaning market makers have actually committed more capital, not just benefited from a cheaper asset.
Altcoins suffer because they lack the same institutional pull. Many of the tokens in the basket trade on fewer venues, have less transparent order books, and attract less hedge‑fund or custodian interest. When market makers pull back, the remaining orders are often thin, making the market more sensitive to even modest sell pressure. Spot‑trade volume follows the same pattern: without deep order books, traders are reluctant to place large orders, and the overall flow stays muted.
What changes because of it
The rebuilt depth around Bitcoin and Ether means large institutional orders can be executed with less price impact. In practice this usually translates into lower slippage for investors moving tens of millions of dollars, and it reduces the likelihood of a repeat flash crash triggered by a single large trade.
For altcoin holders, the picture is less encouraging. Shrinking dollar‑depth and stagnant spot volume suggest that price discovery will stay volatile, especially when a coordinated sell‑off hits the market. Tokens that rely on speculative retail flow may see larger price swings, while projects that depend on steady funding could struggle to raise capital.
The divergence also signals where future development dollars may flow. As market makers continue to favor majors, new DeFi protocols, lending platforms, and tokenized assets will likely be built on or linked to Bitcoin and Ether to tap the deeper liquidity pools. Altcoins that cannot secure a stable market‑making partnership may find themselves priced primarily by sentiment rather than fundamentals.
From a broader perspective, the split recovery hints that crypto’s “institutionalization” is advancing unevenly. Major assets are becoming more akin to traditional equities – deep, regulated, and attractive to large players – while the rest of the ecosystem remains a high‑risk, high‑reward playground.
Investors should watch two signals moving forward. First, any sudden contraction in the majors’ depth, especially beyond the 1 % band, would be an early warning of stress in the market‑making network. Second, if altcoin depth begins to climb in dollar terms, it could indicate that market makers are re‑diversifying, perhaps in response to regulatory clarity or new funding sources. Until then, the safe bet remains to allocate capital where the order books are thick, and to treat the rest of the token universe as speculative territory.
