On-chain data show Machi Big Brother turned $152,000 into $12.72 million in three days trading leveraged perpetual futures on Hyperliquid. The account held about $12.9 million in assets, almost entirely USDC, against roughly $103 million in open long positions: $52.4 million in Bitcoin, $44.9 million in Ether and $6.1 million in Hyperliquid HYPE tokens. Its margin ratio was 14.41%. Hyperliquid recorded $12.19 billion in perpetual-futures volume in the 24 hours ending Aug. 22, nearly 30% of the $40.79 billion traded across decentralized perpetual exchanges. Ether’s nearly 30% seven-day gain helped drive the profit, although leverage can magnify losses just as quickly. Lookonchain says Machi has faced liquidation nearly 500 times, including seven liquidations in 10 hours in June. Hyperliquid’s rules trigger liquidation when equity falls below maintenance margin, with maximum leverage ranging from 3x to 40x and large positions closed in 20% increments. The account’s latest gains show how a trader can recover rapidly despite a long liquidation history, while underscoring the risks of concentrated leveraged exposure.
