The crypto market has had no shortage of wild stories in 2026 but perhaps one of the most engaging is the saga of Jeffrey Huang aka Machi Big Brother. OnchainLens pointed out that a partial liquidation on one of Huang’s 25 times leveraged long position on ETH would leave him just $30,000 away from liquidating on a position worth over $30 million. The numbers are staggering, the story is darkly watchable, and there are key lessons for any trader who has felt the allure of extreme leverage.
From $44M Up to $30M Down – The Full Arc of a Catastrophic Trade
To grasp the significance of this moment requires a rewind to September 2025, back to when Ethereum was hovering around $4,700. At one stage, Machi was sitting on over $44.8M profit on his leveraged ETH campaign, a position that at the time looked like genius. Then the market flipped on him. As ETH cascaded towards $1,800 following a 37% rollover over 30 days, Machi was hit with full liquidation on his 25x leveraged long, suffering over $29M in losses.
The calculations for 25x leverage show a severe loss: a decrease of only 4% on your position will result in losing your margin completely. Instead of stepping back from this trade, Huang chose to increase his investment by sending HyperLiquid an extra 210,000 USDC to support what he felt was a strong conviction trade, and he unfortunately lost that money too. By the end of January 2023, Machi was said to have lost around $71 million after 4 consecutive months of active trading on that platform.
HyperLiquid and the On-Chain Transparency Problem
The blockchain tracking platform Arkham has a publicly visible record of all the transactions associated with the wallet and the wallet’s user. In addition to multiple margin deposits and increasing positions, the wallet is also associated with numerous liquidation events related to ETH perpetual contracts. All of these transactions are currently publicly accessible.
This is the double-edged sword of DeFi, HyperLiquid’s transparent order flow means every deposit, every liquidation and re-entry are all visible in real-time. For traders like Huang, every losing trade is public to the wider crypto community. In February 2026, over a 24-hour period, more than 158,000 traders were liquidated across exchanges, with Ethereum contributing $205.68 million to a total of $595 million in liquidation.
What This Means for Leverage Trading and for ETH
Machi’s case has reignited debate about extreme leverage in crypto markets. Across the network, the liquidation count when Machi re-entered last week sat at about $354 million in a single 24-hour period, mostly from overleveraged longs getting swept up as prices fell. That cascading sell-off, where liquidated longs liquidate existing positions exacerbating price declines that liquidate more longs, is one of the most destabilizing forces in digital asset markets.
At a base level, Machi’s repeated 25x ETH longs reflect a belief that ETH is really undervalued. That thesis may indeed prove correct, but as CoinDesk noted when covering a separate $220M single-position wipe on HyperLiquid, a combination of thin liquidity and forced liquidation mechanics can leave even the correct long-term views worthless in the face of volatility.
Conclusion
Machi Big Brother’s experience exemplifies how conviction trading can lead to disaster and illustrates the harshness of decentralized derivative markets. Being right about the direction of an asset is simply not sufficient when trading with leverage in cryptocurrency or any other derivatives market; having the right time, position size, and the discipline to endure a potentially drawn-down position differentiate successful and unsuccessful traders. After a long wait, the market has finally delivered these lessons at a huge cost with $30 million on the line.
