On-chain monitoring platform Hyperbot detected that an address tagged as “Machi Big Brother” opened a new 25x leveraged Ethereum long position. Such high leverage means the notional position value greatly exceeds the margin, and even a tiny adverse price move can force a liquidation. Shortly after, the position suffered a partial liquidation due to price volatility — a portion of the contracts were forcibly closed, while the remainder stayed open.
In futures trading, when losses push the margin ratio below the exchange's maintenance margin level, liquidation is triggered. In a partial liquidation, only enough contracts are closed to bring the margin ratio back to a safe level, reducing the impact on the market and leaving the rest of the position intact. After this event, the majority of Machi Big Brother's long position remained alive.
Rather than exiting the trade, the address began a series of incremental buys immediately after the partial liquidation. According to Hyperbot's latest data, the position has grown to 1,825 ETH, with an unrealized loss of approximately $40,000 and a return on investment (ROI) of -29.24%. The liquidation price stands at $1,743, meaning that if ETH drops to this level, the remaining contracts will be fully liquidated. The additional buys did not alter the liquidation price, indicating limited margin top-ups and that leverage risk remains elevated, while the larger position size also magnifies potential downside.
