Bitcoin and Ether Liquidity Rebuilds One Year After Crash

Update (Oct 10, 12:03 UTC): One year after the Oct. 10, 2025 liquidation event, Bitcoin and Ethereum order books have deepened beyond pre-crash levels, whereas altcoin liquidity continues to steadily erode.

Nearly a year after bitcoin's October 2025 crash triggered $19 billion in liquidations, analysts and market experts warn that the underlying risks driving the selloff remain present across crypto markets, according to CoinDesk.

Just days after hitting a record high above $126,000 on October 10, 2025, bitcoin plunged from approximately $122,000 to $105,000, with a vast portion of the decline occurring within minutes. The violent move caught market participants off guard following months of sustained bets on higher prices.

Derivatives Drive Near-Term Action

According to Mark Connors of Risk Dimensions, coming into the crash, open interest sat near historic highs as traders piled into bullish positions anticipating a continuation of historical four-year cycles. Connors noted that the sharp downward movement was driven primarily by derivatives rather than onchain data, signaling that paper bitcoin and leveraged products continue to dictate near-term price direction.

Perpetual futures, which allow traders to speculate on price action without holding the underlying asset, remain a central fixture of crypto trading alongside strong financial incentives from exchanges to maintain these products.

Better Visibility and Risk Management

While market structure risks persist, analysts suggest that traders are now better equipped with improved visibility into order books and positioning data to help define market conditions.

Chris Sullivan, co-founder of Hyperion Decimus, advised market participants to avoid leverage entirely, closely monitor open interest, funding rates, and sentiment metrics, and exercise patience when those indicators reach extremes. For long-term holders, Sullivan recommended purchasing bitcoin and transferring holdings off exchanges into self-custody.
