According to Cas Abbé on Twitter, a prominent Bitcoin whale trading at 40x leverage has seen their all-time PNL flip from $87 million in profit to a $1.9 million loss, highlighting the risks of high-leverage trading strategies. The post also suggests that market makers may be holding back significant market pumps until this large position is fully liquidated, which could affect near-term Bitcoin price volatility and impact overall crypto market sentiment (source: Cas Abbé Twitter, May 28, 2025). Traders should monitor whale liquidations closely as these events often precede significant price movements and shifts in liquidity.
