According to Ai 姨 (@ai_9684xtpa) on Twitter, James Wynn has opened a significant short position on Bitcoin, totaling 5,877 BTC or approximately $629 million, at an entry price of $107,061.6. Notably, after Wynn's massive short, the BTC perpetual contract funding rate shifted from positive to negative, indicating a surge in short interest and increased market volatility. This shift means traders are now paying funding fees regardless of position direction, reflecting heightened pressure from large positions and potential for abrupt price swings. These developments are critical for traders monitoring funding rates, open interest, and possible liquidation cascades in the crypto derivatives market (Source: @ai_9684xtpa, Twitter, May 25, 2025).
