According to Lookonchain, the obituary for Zerebro developer Jeffy Yu was published on the Legacy website on May 6, 2025, confirming his passing. Shortly after, a timed article from Zerebro DEV claimed that $LLJEFFY was Yu's final art piece. Simultaneously, both Zerebro's official X (formerly Twitter) account and Jeffy Yu's personal X account were deactivated. These events have resulted in significant volatility and uncertainty around the $LLJEFFY token, with trading volumes spiking as investors react to the news. The sudden leadership vacuum and project uncertainty may impact $LLJEFFY's short-term price and liquidity, prompting caution for crypto traders evaluating exposure to this asset (Source: Lookonchain, May 7, 2025).
