Machi Big Brother Boosts 25x Ether Long to $9.2 Million

Taiwanese crypto trader Jeffrey Huang, widely known as Machi Big Brother, has drawn renewed attention over the performance of his perpetual-futures account. Returns on leveraged positions can be distorted when a rebound from a deeply depleted balance is compared only with the account’s low point, without accounting for additional capital deposits or earlier losses. That distinction is central to assessing whether the reported gains represented investment profit or merely a recovery of funded capital.

Huang recently rejected a Taiwanese media report claiming he had generated an 84-fold return. On-chain data showed the account had previously lost 99% of its value before rebounding by nearly NT$300 million over five days as Ether and other crypto assets advanced. However, cumulative net deposits into the account totaled about NT$841 million, indicating that the headline return differed sharply from a calculation based on Huang’s total committed capital.

Prominent crypto investor Jeffrey Huang, known as “Machi Big Brother,” has long traded on decentralized perpetual futures exchange Hyperliquid, frequently taking highly leveraged long positions in ETH. Such strategies are vulnerable to liquidation during sharp price swings, keeping the crypto community focused on his account activity and risk tolerance.

Over the past year, Huang’s Hyperliquid account has accumulated losses of more than $77 million, equivalent to about NT$2.52 billion. ETH recently came close to $2,000, and several leveraged long positions were liquidated, leaving the account with a balance of only about $100,000. The market is also watching whether he has stopped adding margin.

Prominent crypto trader Jeffrey Huang, known as “Machi Big Brother,” has long used high leverage to trade crypto assets including Bitcoin (BTC), Ethereum (ETH) and Hyperliquid’s HYPE token. Such positions can amplify gains when prices rise but also risk forced liquidation during sharp declines, making his holdings closely watched by the market.

Huang recently re-entered the market with long positions in BTC, ETH and HYPE and currently has more than $1.4 million in unrealized gains. However, his cumulative losses since June 2025 reached as much as $29 million, including a weekly loss of $1.42 million. He also added to a 25x-leveraged ETH long position and remains about $27.2 million short of breaking even overall.
