What caused the BTC flash crash and mass liquidations?
BTC flash crash refers to the rapid price drop below $110,000 that triggered a cascade of forced exits across perpetual futures markets. Rapid deleveraging removed approximately $47M in long positions, elevating short-term volatility and briefly depressing BTC price action before a partial recovery.
Risk-taking trader James Wynn experienced another round of liquidations during the swift downturn. Wynn returned to the Hyperliquid platform shortly after its largest liquidation event earlier in October, positioning sizable long exposure that was closed when the flash crash hit.

BTC had another flash crash to under $110,000, causing a wave of long liquidations, as trader James Wynn lost all his long positions on Hyperliquid. | Source: Coingecko
How was James Wynn liquidated in the flash crash?
James Wynn’s positions—spanning BTC, ETH and PEPE—were forcibly closed after price action moved sharply against leveraged longs. Wynn reported losses of roughly $142,000 stemming from positions he re-established on Hyperliquid on October 15 and held into the volatile session on October 16. The liquidation deployed standard margin engine mechanics on the perp DEX, matching price slippage to margin thresholds and closing at-market to preserve counterparty solvency.
On-chain data and platform metrics (Hyperliquid reporting) show the event coincided with elevated orderbook gaps and concentrated long exposure among whale wallets. CoinGecko price feeds and exchange-level aggregates recorded the dip and subsequent rebound, corroborating the scale of liquidations and the intraday volatility spike.
