According to Ai 姨 (@ai_9684xtpa), Hyperliquid's liquidation mechanism for Bitcoin involves a partial forced closure of long positions when price triggers liquidation, rather than voluntary position reduction. This process ensures maintenance margin meets the platform's minimum requirements and may impact leverage trading strategies, as traders must monitor margin levels closely to avoid forced liquidations.
