The Oct. 10, 2025, crypto market crash triggered around $19 billion in liquidations of leveraged positions, with Bitcoin falling from approximately $122,000 to $105,000 after setting a record high above $126,000.

Mark Connors of Risk Dimensions, who previously worked on hedge fund positioning products at Credit Suisse, said excessive positioning remains a key source of risk in the crypto market. Open interest was approaching historical highs before the sell-off, as bullish investors predicted Bitcoin could reach $250,000 to $400,000 by following patterns from previous four-year cycles.

Connors said derivatives markets, rather than on-chain transactions, were largely responsible for the sharp decline. He emphasized the growing role of “paper bitcoin,” or financial contracts that can influence Bitcoin’s price without requiring traders to buy or sell the actual cryptocurrency. Perpetual futures continue to account for a significant share of trading, while exchanges benefit from offering leveraged products.

More detailed order-book information and positioning data have given traders better ways to evaluate market conditions. Nevertheless, Chris Sullivan of Hyperion Decimus urged investors to avoid leverage and monitor open interest, funding rates and market sentiment. He also advised long-term holders to consider self-custody and keeping their Bitcoin away from exchanges.

The possibility of another major liquidation event remains as long as leveraged products continue to be widely used.

The crash also cast doubt on the reliability of Bitcoin’s traditional four-year market cycle. Connors said the pattern has evolved and become less useful as a forecasting indicator, with macroeconomic trends and political developments increasingly affecting prices.

Even as institutional investment products gain traction, derivatives remain a major force behind Bitcoin’s short-term movements. The episode highlighted why traders need to understand market positioning and leverage, rather than relying solely on historical cycles or long-term investment narratives.
