After being liquidated nearly 500 times, Machi Big Brother finally began to make money.

Written by: angelilu, Foresight News

As the market warmed up, the undercurrents on the chain had long since surged into waves. Machi Big Brother once again became the protagonist of the on-chain public opinion arena.

Over the past ten months, this crypto whale has been submerged under nearly every surge, with a history of continuous losses resembling a heavy report card. But just last week, during a one-sided market, with a principal of $150,000, he managed to roll out a long position worth $12.72 million within three days using extreme leverage, with a single profit reaching as high as $12.5 million, and his principal multiplied by 84 times.

As of August 24 at 6 PM, the total assets of the machibigbrother.eth account on the Hyperliquid address were fixed at $10.07 million, with an underlying long position of $124 million. Leverage is like a suspended thread, and positions are like heavy hammers—this individual's account fluctuations are precisely a condensed slice of current market sentiment, liquidity games, and risk preferences. The on-chain numbers do not lie, recording both enthusiasm and calm within the position figures.

Current Position: 10 Million Supports 133 Million

Different analysts have slightly different opinions. According to analyst Yujin data, Machi Big Brother has accumulated a loss of $35 million in long positions on ETH over the past 10 months, which has narrowed to about $24 million after this profit.

From the real-time data on HypurrScan, his current position composition can be more clearly observed (data retrieved as of August 24, 2026, 6:00 PM):

The four positions total $123.72 million, with an overall floating profit of about $1.435 million calculated at the current price. However, breaking it down: HYPE, BTC, and PUMP have all fallen below their breakeven prices, with only ETH still above its breakeven price by 2.9%. All profits are actually supported by this ETH position (with a floating profit of about $2.36 million), while the other three positions have a combined floating loss of $920,000.

Furthermore, to maintain these four long positions, he has accumulated payment of about $256,000 in funding fees—this is the cost of holding perpetual contracts, deducted hourly regardless of price movement, and the longer the position is held, the more is deducted.

The key concern is the "liquidation price"; once the price falls here, the system will automatically sell his position without his consent to stop losses. The tightest among the four is ETH—$2,229, about 10% away from the current price. This ETH position alone accounts for 59% of his total position, which is the dead line for the entire account.

Converted into leverage: $9.44 million of principal supports a position of $123.72 million, with an overall leverage of about 13.1 times. This means that as long as ETH drops from $2,463 to $2,229, a decline of $234, then the $12.5 million he earned in the past 3 days, along with the previous principal, will go to zero.

Strategy Remains Unchanged, Risks Still Exist

It is important to note that Machi Big Brother's profit this time came from continuous "rolling positions." "Rolling positions" refer to opening a leveraged position without withdrawing floating profits but allowing them to directly serve as new margin, automatically supporting larger positions; as prices rise, positions expand again, compounding like this.

Its mathematical characteristic is that—when winning, it is exponential, but when losing, it is one-time. Since each increase in position is based on the previous floating profit, once the market turns against him, not only the principal is deducted, but all the profits accumulated in the process are deducted at the same time. Turning $150,000 into $11.15 million requires consecutive correct bets several times; reverting $11.15 million back to $150,000 theoretically only requires one time.

Last week, ETH rebounded from the bottom, providing this structure with the most ideal environment: one-sided, continuous, and without looking back.

Although this operation yielded him a floating profit of $11 million, we must not forget that as the "on-chain liquidation champion," Machi Big Brother has repeatedly faced situations where significant profits rapidly turned into huge losses. In mid-September 2025, his peak account was once close to $60 million (with floating profits exceeding $44-45 million). Subsequently, during the market crash on October 11, positions in XPL, ETH, and others were liquidated, turning profits of about $15 million into losses of over $11 million, with profits evaporating quickly.

His trading style is characterized by high leverage (often 25x–40x), extreme bullishness, high win rates but poor risk-reward ratios, and adding margin/supplementing positions when losing instead of stop-loss, resulting in "small wins and large losses" and frequent liquidations.

In November 2025, Lookonchain monitored that he was forcibly liquidated 71 times in a single month on Hyperliquid, ranking first in the entire network.

Currently, he still has a historical cumulative loss, and issues with trading discipline have not fundamentally changed. On-chain data is publicly transparent but subject to violent fluctuations.

Two Weeks of Selling Bored Apes to Supplement Margin

One highlight of this story is Machi Big Brother's inherent aura, while another highlight tells the story of using a small principal to gamble on a large position. But if we rewind two weeks back, he was selling Bored Apes one by one:

On August 5, sold BAYC #5670 for 9 ETH—his purchase cost over three years ago was 84.99 ETH, a loss of 89.4%;

On August 13, sold BAYC #5715 for 8.3 ETH, about $15,500; the initial cost was 34.17 ETH, about $64,600, a loss of 75.7%.

This was his daily routine in the first half of August.

The cheap sales of BAYC can be traced back even further; according to Lookonchain, he lost money selling 34 BAYC in June, exchanging them for about 326 ETH, but with an overall loss of about 399 ETH, mainly to supplement margin for high-leverage ETH long positions on Hyperliquid, to avoid or delay liquidation. The community thus joked that he was "selling monkeys to stay alive."

As of the publication of this article, according to OpenSea data, he holds a total of 4,357 NFTs, but the value of the NFT portion has dropped to only $3.17 million, including 128 BAYC (approximately $2.5 million) and 102 MAYC (approximately $288,000). In comparison, at his peak, he had heavily invested in 300 BAYC.
