Crypto trader Machi Big Brother experienced a dramatic collapse of his trading account, losing over 99% of his $12.25 million position during a recent market selloff. According to blockchain analytics platform Lookonchain, the trader, whose real name is Jeffrey Huang, was fully liquidated on October 15 after a series of leveraged trades went against him. The account had been used to trade perpetual futures on Hyperliquid, where traders can borrow exposure to take positions larger than their available collateral. The account's near-total retreat shows how quickly leveraged gains can disappear when market conditions turn against positions.
As reported by Lookonchain, Machi had transformed his initial $56,000 investment into more than $12 million over a four-month period before the dramatic reversal. The platform documented the trader's account balance dropping from the reported peak of $12.25 million to approximately $21,787.78 following the liquidation. This decline represents a complete loss of the substantial gains accumulated during the preceding four months of trading activity, with the account-value decline being approximately 99.8% of the reported peak. The scale of the gain and speed of subsequent loss place this case among the more extreme examples of leveraged crypto trading outcomes in recent memory, highlighting how volatile markets can compress months of gains into single trading sessions.
The liquidation occurred as Bitcoin dropped below $81,000 and Ethereum approached $2,380 amid heavy selling pressure across the cryptocurrency market. According to crypto.news, another liquidation wave on October 14 had erased approximately $811 million in leveraged positions, with open interest remaining near $140.9 billion after the selloff. The selling pressure had been building since the previous week, when crypto liquidations reached $1.09 billion in the 24 hours leading to October 9, with long positions accounting for approximately $1.05 billion of that total. Macro pressure added to the risk-off move, with September annual inflation reported at 3.7%, above the 3.6% market forecast, which can weigh on risk assets by reinforcing expectations of tighter monetary conditions.
Despite the significant losses, Machi reportedly returned to trading shortly after the liquidation, opening another leveraged Ethereum long position with 25x leverage. This decision to reopen a position with such high leverage left the trader exposed to further price movements in the cryptocurrency, highlighting the risks associated with high-leverage trading strategies in volatile markets. The next concrete risk marker is Ethereum's price relative to the new long, without verified position terms, its liquidation threshold remains unknown, leaving the trader vulnerable to another sharp decline. The case underscores how extraordinary short-term gains, especially those built through leverage, carry commensurate downside risk, with the same volatility that can turn a modest stake into millions just as quickly reversing that outcome.
