The sharp crypto market crash in October marked a turning point for professional traders, wiping out billions and dismantling strategies that had powered easy profits for years, according to crypto exchange BitMEX.
In its State of Crypto Perpetual Swaps in 2025 <a style="color: #0000ff;" href="https://www.bitmex.com/blog/state-of-crypto-perps-2025" rel="noopener noreferrer nofollow">report</a> released Thursday, BitMEX said the market turmoil between October 10 and 11 erased roughly $20 billion and represented the most damaging event ever for sophisticated crypto market makers.

 From the $20bn Oct crash to the death of “easy” funding yield, the game has changed.

The exchange explained that a cascade of auto-deleveraging mechanisms, where exchanges forcibly unwind leveraged positions to protect themselves, shattered market makers’ traditionally “safe” delta-neutral strategies. As a result, liquidity providers pulled back en masse, leaving crypto order books dangerously thin.

Market makers typically reduce risk by holding spot assets while maintaining offsetting short positions. During the October <a style="color: #0000ff;" href="https://defi-planet.com/2025/10/crypto-market-reclaims-4-trillion-as-eth-bnb-doge-lead-post-crash-rally/" rel="noopener noreferrer nofollow">crash</a>, however, auto-deleveraging systems closed those hedges without warning, leaving firms exposed to falling prices.
BitMEX said this breakdown of the neutrality promise forced market makers to exit markets throughout the fourth quarter, pushing order book depth to its lowest levels since 2022.
The exchange added that the once-lucrative funding rate trade, which involved arbitrage pricing differences between spot and perpetual futures, has become overcrowded. Funding yields have fallen to around 4%, underperforming even U.S. Treasury bills and effectively ending a long-running source of easy yield.

The report also highlighted a growing divide among exchanges, separating “fair-matching” platforms from so-called B-Book exchanges, where platforms act as counterparties to user trades and reserve the right to cancel profitable positions under vague trading rules.
According to BitMEX, distrust of such practices has driven traders toward high-performance decentralized perpetual exchanges like Hyperliquid. However, the exchange warned that decentralization alone does not eliminate manipulation risks.
BitMEX pointed to the September launch of the Plasma (XPL) token, where attackers exploited transparent on-chain data and weak price oracles to trigger liquidations across perpetual positions. The incident, it said, showed that transparency does not automatically translate to user protection.
Despite the upheaval, BitMEX argued the shakeout may ultimately strengthen the industry by clearing out fragile platforms and paving the way for more resilient exchanges and genuine innovation.
