What Happened to the Hyperunit Whale?
A crypto trader linked to former BitForex CEO Garrett Jin has fully exited a highly leveraged ether position on Hyperliquid, locking in losses of roughly $250 million, according to on-chain data from Arkham. The account now holds just $53, marking a sharp collapse for a trader who became widely known after earning around $200 million by shorting bitcoin and ether ahead of the October 2025 tariff-driven market selloff.
The trader, often referred to as the “Hyperunit whale,” had spent recent months building an aggressive ETH long that at its peak exceeded $700 million in notional value. That exposure unraveled this week as ether prices fell sharply, forcing a full exit and erasing most of the capital accumulated after last year’s highly timed short trade.
Arkham data shows the Hyperliquid position has now been fully closed. While the trading account retains other crypto holdings elsewhere, the collapse of the ETH position represents one of the largest realized losses recorded on a decentralized perpetuals platform.
Investor Takeaway
From October Windfall to January Unraveling
The trader first drew attention in October 2025 after opening large short positions in bitcoin and ether just minutes before President Trump announced a 100% tariff on Chinese imports. The announcement triggered a sharp market drop and more than $18 billion in liquidations across crypto markets, according to industry estimates.
Those short positions, which exceeded $1 billion in combined notional exposure, generated profits estimated at roughly $200 million. The timing of the trades sparked speculation about information advantages, though no evidence of wrongdoing has been established.
Wallet analysis later linked the activity to addresses associated with Garrett Jin, the former chief executive of BitForex. Jin denied owning the funds but acknowledged familiarity with the trader behind the positions, saying, “the fund isn’t mine – it’s my clients’.”
Following that episode, the trader reversed course. By mid-January, Arkham data showed a rapidly expanding long exposure across multiple assets, with ether accounting for the largest share. At its height, the ETH position alone was valued at more than $730 million, while combined exposure across ETH, SOL, and BTC surpassed $900 million.
Why the Ether Trade Collapsed
The unwind came as ether prices weakened throughout January before sliding sharply this week. ETH fell roughly 10% in a 24-hour period, trading near $2,400 at the time the position was closed. On-chain analysts had already flagged the whale’s leverage as increasingly fragile as prices drifted lower.
Earlier this week, unrealized losses on the ETH long were reported to exceed $130 million. As volatility accelerated, the margin cushion eroded, leaving little room to absorb further downside. The final exit crystallized losses estimated at around $250 million, turning one of last year’s most visible crypto winners into one of 2026’s most dramatic reversals.
The episode highlights how quickly leveraged positions can unravel on perpetual futures venues, particularly during periods of thin liquidity and rapid price swings. Unlike spot markets, leveraged trades amplify both gains and losses, compressing the window for recovery once prices move against the position.
Investor Takeaway
What This Says About Leverage in Crypto Markets
The Hyperunit whale’s collapse arrives at a time when leverage across crypto derivatives has again become elevated. Decentralized platforms have made it easier for large traders to deploy massive positions with fewer gatekeepers, but that access also concentrates risk during fast market moves.
While the trader still controls significant assets outside the closed Hyperliquid account, the loss underscores how leverage can reverse fortunes even after headline-making wins. The October short trade demonstrated the upside of aggressive positioning. The ETH long shows the downside when conviction collides with price momentum.
