Woofun AI reports that Machi Big Brother, a prominent crypto whale known for his volatile trading history, executed a high-leverage trade on Hyperliquid that transformed $150,000 into $12.72 million in just three days. This rapid capital expansion, achieved during a recent market recovery, has drawn significant attention to his account, machibigbrother.eth, and his ongoing reliance on extreme leverage strategies. The trader's recent success stands in stark contrast to his historical performance, which has been marked by substantial losses and frequent liquidations, highlighting the precarious nature of his trading approach. His portfolio, which includes significant holdings in Bored Ape Yacht Club (BAYC) NFTs, has been liquidated to fund these speculative positions, underscoring the high-stakes environment in which he operates.

The core of this recent financial maneuver involved deploying an initial capital base of $150,000 to establish a long position that grew to $12.72 million within a 72-hour window. This operation generated a single profit of $12.5 million, representing a return of more than 84 times the initial investment. The speed and magnitude of this gain were facilitated by the use of extreme leverage, allowing the trader to amplify his exposure to market movements. Such a dramatic increase in capital value in such a short period is rare and indicative of the high-risk, high-reward dynamics prevalent in decentralized finance markets. The success of this trade was contingent upon a sustained upward trend in the underlying assets, particularly Ethereum, which provided the necessary momentum for the leveraged position to compound.

As of 6:00 PM on August 24, the machibigbrother.eth account on Hyperliquid held total assets valued at $10.07 million. This balance was supported by additional long positions worth $124 million, illustrating the scale of the trader's exposure to the market. The disparity between the account's net assets and the total value of its positions highlights the extent of the leverage being employed. This structure means that even minor fluctuations in asset prices can have significant impacts on the account's equity. The high level of exposure also increases the risk of liquidation, as the trader must maintain sufficient margin to keep the positions open. The current state of the account reflects a delicate balance between potential gains and the threat of total loss.

Historical data reveals that over the past 10 months, Machi Big Brother has incurred cumulative losses of $35 million from trading long ETH positions.

However, the recent profit of $12.5 million has reduced this figure to approximately $24 million. Real-time data from HypurrScan, as of August 24, 2026, provides a detailed view of his current position composition. The trader's net position remains negative, indicating that despite the recent success, he has not yet recovered from previous losses. This context is crucial for understanding the overall financial health of the account and the sustainability of his trading strategy. The persistent losses suggest that the trader's approach may not be viable in the long term, despite occasional periods of significant profit.

The trader's current portfolio consists of four specific asset positions, with a combined total value of $123.72 million. At current prices, these positions yield an overall unrealized profit of about $1.435 million. A breakdown of the individual assets shows that positions in HYPE, BTC, and PUMP have all fallen below their break-even points. In contrast, the ETH position remains 2.9% above its break-even point, contributing an unrealized profit of approximately $2.36 million. The other three positions collectively result in an unrealized loss of $920,000. This distribution of profits and losses underscores the trader's heavy reliance on ETH for generating returns. The performance of the ETH position is critical to the overall success of the portfolio, as it offsets the losses incurred in other assets.

Woofun AI data shows that to maintain these four long positions, the trader has paid approximately $256,000 in fees, which are the holding costs associated with perpetual contracts. These fees are deducted hourly, regardless of price changes, and increase with the duration of the positions. The most critical factor in this setup is the forced liquidation price; if the asset price drops to this level, the system will automatically sell the positions to implement a stop loss.

Among the four positions, ETH has the tightest liquidation threshold at $2,229, which is about 10% below the current price. ETH alone accounts for 59% of the total positions, making it the primary risk factor for the entire account. In leverage terms, $9.44 million in capital supports $123.72 million in positions, resulting in an overall leverage of around 13.1 times. This means that if ETH falls from $2,463 to $2,229—a drop of $234—the trader will lose not only the $12.5 million profit but also the original capital, bringing the account back to zero.

The recent profit was achieved through a strategy known as 'position rolling,' where unrealized profits are used as additional margin to support larger positions. As prices rise, the positions grow, creating compounding effects. This strategy allows for exponential gains but also exposes the trader to simultaneous losses if the market turns. It takes multiple consecutive successful trades to turn $150,000 into $11.15 million, but theoretically, just one loss can reduce $11.15 million back to $150,000. The recent rally in ETH provided an ideal environment for this strategy, characterized by a one-sided, continuous upward trend with no reversals. Although this operation generated an unrealized profit of $11 million, the inherent risks of position rolling remain significant, as any market downturn could erase these gains instantly.

Machi Big Brother has a history of experiencing rapid shifts from large profits to huge losses, earning him the title of 'champion of on-chain liquidation.' At the peak in mid-September 2025, his account value approached $60 million, with an unrealized profit of over $44–45 million.

However, during the market crash on October 11, long positions in XPL, ETH, and others were liquidated, turning a profit of about $15 million into a loss of over $11 million. His trading style is characterized by high leverage, often ranging from 25x to 40x, and an extremely bullish approach. He has a high win rate but a poor risk-reward ratio, frequently adding margin or buying more assets instead of using stop losses when losing. In November 2025, Lookonchain tracked 71 forced liquidations of his positions on Hyperliquid in just one month, the highest number in the entire network. This pattern of behavior suggests a lack of disciplined risk management.

To fund his trading positions, Machi Big Brother has been selling off Bored Ape Yacht Club (BAYC) NFTs. On August 5, he sold BAYC 5670 for 9 ETH, despite its purchase cost over three years ago being 84.99 ETH, resulting in a loss of 89.4%. On August 13, he sold BAYC 5715 for 8.3 ETH, worth about $15,500, while its original cost was 34.17 ETH, or about $64,600, meaning a loss of 75.7%. This selling activity was part of his routine in the first half of August. The selling of BAYCs dates back even further; in June, he sold 34 BAYCs at a loss, receiving about 326 ETH, but overall losing about 399 ETH. These sales were primarily intended to provide margin for his highly leveraged ETH long positions on Hyperliquid and to avoid or delay liquidation. The community has joked that he is 'keeping himself afloat by selling monkeys,' highlighting the desperation behind his asset liquidations.

As of the time of writing, Machi Big Brother holds a total of 4,357 NFTs, but their combined value is only $3.17 million. This portfolio includes 128 BAYCs, worth about $2.5 million, and 102 MAYCs, worth about $288,000. For comparison, at his peak, he once held 300 BAYCs. The significant reduction in his NFT holdings reflects the ongoing pressure to liquidate assets to support his trading activities. This trend suggests that his reliance on NFT sales to fund leveraged positions may continue, further eroding his long-term wealth. The current state of his portfolio indicates a precarious financial position, with high exposure to market volatility and a history of substantial losses.
