Machi Big Brother turns $150,000 into $12.72 million with high-leverage rolling longs

Machi Big Brother turned $150,000 of capital into a $12.72 million long in three days, according to a Foresight News report. The trade generated about $12.5 million in profit and lifted the original capital by 84 times. As of Aug. 24 at 18:00, the Hyperliquid address machibigbrother.eth held $10.07 million in assets and roughly $123.72 million in long positions. The report says his four open positions were worth $123.72 million in total, with ETH carrying the bulk of the risk. ETH was the only leg still above break-even, while HYPE, BTC and PUMP had already fallen below their respective break-even prices. The report also said he had paid about $256,000 in funding fees to maintain the four longs. ETH was the tightest position, with a liquidation price of $2,229, about 10% below the quoted market price of $2,485.6 in the article’s reference data. ETH also accounted for 59% of the total position size. The structure was built through rolling leverage: instead of taking profits off the table, unrealized gains were used as additional margin to support larger positions. That setup can work very well in a one-way rally, but it also means losses can compound quickly if the market turns. Foresight News cited analyst data showing that Machi Big Brother had lost $35 million on ETH longs over the past 10 months, narrowing the cumulative loss to about $24 million after the latest gain. The report also noted that in mid-September 2025, his account had approached $60 million at its peak, before a market crash on Oct. 11 wiped out much of the profit and pushed the position back into a loss of more than $11 million. His trading style, the report said, has been defined by 25x to 40x leverage, a persistent long bias, a high win rate but poor risk-reward profile, and frequent margin top-ups instead of stops. Lookonchain also tracked 71 forced liquidations on Hyperliquid in November 2025, the highest number across the network. The same report tied part of his recent margin management to NFT sales. On Aug. 5, he sold BAYC #5670 for 9 ETH, far below the 84.99 ETH he paid more than three years earlier. On Aug. 13, he sold BAYC #5715 for 8.3 ETH, or about $15,500, after buying it for 34.17 ETH. Lookonchain also said he sold 34 BAYC in June at a loss to add margin for his Hyperliquid ETH longs and delay liquidation. OpenSea data cited in the report showed 4,357 NFTs in his wallet, valued at about $3.17 million, including 128 BAYC and 102 MAYC. At his peak, he reportedly held about 300 BAYC.
