Jeffrey Huang, the crypto trader known as Machi Big Brother, saw his Hyperliquid account suffer a near-total collapse after a liquidation event on October 15, 2026, reduced its value from a peak of $12.25 million to approximately $21,000.
Lookonchain reported that Huang had turned $56,000 into $12.25 million over a four-month trading period. The account’s balance later dropped to about $21,800, erasing nearly all of its peak value. The reversal illustrates the substantial risks of using leverage in volatile cryptocurrency markets.
The liquidation coincided with a wider selloff in crypto derivatives. Bitcoin fell below $81,000, while Ethereum moved toward $2,380. When leveraged positions move against traders, losses can deplete collateral and push margin levels below exchange requirements. This can force positions to close and add further sell pressure to a declining market.
Bitget Research estimated that approximately $811 million in crypto derivatives positions were liquidated on October 14, with open interest remaining near $140.9 billion after the downturn. A separate 24-hour liquidation wave leading into October 9 reached $1.09 billion, of which roughly $1.05 billion came from long positions. The figures highlight how heavily bullish traders can be affected when prices fall sharply.
Economic uncertainty also contributed to the market weakness. September’s annual inflation rate reached 3.7%, above the 3.6% forecast. A hotter inflation reading can weaken expectations for interest-rate cuts and increase concerns that restrictive monetary conditions will persist, putting additional pressure on risk assets, including cryptocurrencies.
Ethereum investment products faced another headwind as well. U.S. spot Ether ETFs recorded $542.2 million in weekly outflows for the week ending October 9. With Bitcoin trading below $81,000 and Ether nearing $2,380, Huang’s losses occurred amid broader pressure on cryptocurrency prices and leveraged market exposure.
Bitcoin’s Key Support Zone Comes Under Pressure
Bitcoin’s $80,000–$81,000 range became a major focus after BTC dropped below $81,000. A move beneath a closely monitored support level can encourage traders to reduce their positions and trigger stop-losses or forced liquidations, potentially amplifying downward price movements.
From a $56,000 Starting Balance to a 99.8% Decline
Huang’s reported trading performance shows how quickly a substantial gain can disappear. His account reportedly grew from $56,000 to $12.25 million over four months before falling to approximately $21,800. That represents a decline of about 99.8% from the reported peak.
Hyperliquid perpetual futures allow traders to take leveraged positions that exceed the collateral they deposit. If losses reduce the available margin below the required level, positions can be liquidated automatically. The final account balance depends on several factors, including collateral, changes to the position and the prices at which trades are executed.
The distinction between account value and realized profit is important. A trader’s displayed balance can rise significantly while open positions carry unrealized gains. If the market reverses before those gains are secured, liquidation can wipe out much of the account’s value.
Hyperliquid has also attracted significant leveraged Ether trading activity, but other traders’ positions do not establish the specific trades or losses behind Huang’s reported account collapse. Each trading episode requires separate evidence.
After the liquidation, Huang reportedly returned to the market and opened a new Ethereum long position with 25x leverage. The position stands to benefit if ETH rises, but leverage also increases the impact of adverse price movements. At 25x, even a relatively small decline can significantly erode the margin supporting the trade.
Huang’s reported account trajectory—from $56,000 to a $12.25 million peak and then to around $21,800—underscores the dangers of aggressive leverage. The new ETH position creates further exposure to market volatility, although its exact liquidation price cannot be established without confirmed details about its entry price, size, collateral and margin requirements.
