$19 Billion Crypto Crash Shows Market Makers Can Also Break the Market

The October 10-11 crypto crash wasn’t just another market shake-up. 

A $19 billion liquidation wiped out leveraged positions across Bitcoin, Ethereum, and altcoins, leaving traders and exchanges reeling. The headline trigger was Trump’s 100% tariffs on Chinese imports. 

But according to blockchain analyst and Mirror.xyz blogger YQ, the deeper story lies in how market makers – the players supposed to keep the market stable – vanished when they were needed most.

Market Makers: Lifelines That Disappeared

Market makers are meant to keep trading smooth. They provide liquidity, tighten spreads, and help prices stay orderly. In traditional finance, this usually works. Crypto is different. Markets never sleep, liquidity is scattered across hundreds of exchanges, and price swings can be extreme.

YQ’s breakdown shows how fast things unraveled. Between 20:40 and 21:20 UTC, market depth on tracked tokens fell from $1.2 million to just $27,000 – a 98% collapse. 

Bitcoin dropped to $108K, and some altcoins lost 80% of their value. 

“Market makers had 20-40 minutes of warning before complete withdrawal,” YQ notes. They pulled out in a coordinated way, returning only when the market offered a profitable re-entry.

ADL: When the Market Turns on Traders

With order books empty, exchanges relied on Auto-Deleveraging (ADL) to handle positions that couldn’t be closed normally. Binance, Bybit, and Hyperliquid triggered ADL for tens of thousands of accounts. The most profitable traders were hit first. 

Hedge positions disappeared in minutes, open interest across the market fell by roughly 50%, and what looked like a stable portfolio became exposed in a heartbeat.

Why Market Makers Walked Away

YQ points to a clear structural problem. Market makers faced four incentives to pull out: high risk versus small spread profits, early knowledge of a long-biased market, no legal requirement to stay, and bigger profits from arbitrage. 

The result was a vicious cycle: shock, withdrawal which led to depleted insurance funds, and more liquidations.

Lessons for the Market

“Voluntary liquidity provision fails precisely when involuntary provision is most needed,” YQ writes. The $19 billion wipeout, according to him, exposed a system where those meant to stabilize the market can profit more from chaos than from order.

Community reactions reflected the frustration. @JackyGekko asked,

“Why should market makers provide liquidity even when the market is so skewed to the long side…what kind of incentive can cover their losses?” 

The answer is clear: until exchanges create proper safeguards, circuit breakers, and incentives, the next big crash will teach the same lesson.
