According to Lookonchain, the trader identified as '0x51d9' successfully closed a 40x leveraged short position on Bitcoin, realizing a $1.18 million profit (source: Lookonchain, May 12, 2025). This high-leverage trade highlights increased volatility and potential liquidity risks in BTC derivatives markets, signaling that aggressive shorting strategies can still yield substantial returns even in uncertain market conditions. Traders should monitor whale activity and leverage ratios closely, as such large-scale positions may precede significant price movements or liquidation cascades in the broader crypto market.
