Unconfirmed reports are circulating that Jeffy Yu, the 22-year-old founder of the small-cap crypto project Zerebro, has tragically died by suicide during a livestream on Pump.fun on May 4, 2025. While the footage has been widely shared across social media platforms, its authenticity remains unverified at this time.
A disturbing video circulating on X (formerly Twitter) appears to show a young man allegedly Yu smoking a cigarette before fatally shooting himself in the neck. Although the clip has sparked widespread speculation and concern, no official confirmation had been issued by law enforcement as of press time.
On the same day as the reported incident, Yu published a manifesto introducing a new crypto concept called Legacoins a term he coined to describe a class of memecoins rooted in symbolic permanence, legacy, and digital immortality. In the manifesto, Yu emphasized that Legacoins should be governed by a core philosophy: developers are to acquire and accumulate tokens, never to sell or trade them, effectively transforming them into a legacy asset.
“I am the permanent floor,” Yu wrote, suggesting that his personal commitment—and potentially his life—would serve as the enduring support for the value of the token.
Yu launched LLJEFFY, the first Legacoin, on the same day. According to reports, the token employs a bot mechanism that buys and burns tokens at random intervals to create scarcity. His vision for Legacoins included the idea that holdings would become inaccessible upon the holder’s death, theoretically establishing a permanent price floor.
While some within the crypto community expressed condolences and shock, others questioned the authenticity of the event. Skeptics pointed out that Yu had recently announced a new Zerebro album scheduled for release on May 30, prompting speculation that the incident might have been a marketing stunt designed to provoke attention and drive token prices.
However, on May 6, the obituary platform Legacy published a notice confirming the passing of Jeffy Yu on May 4, lending credibility to reports of his death. The crypto community has since been divided, with some mourning the loss of an experimental thinker and others grappling with the implications of his final message.
Meanwhile, the ZEREBRO token has surged roughly 85% over the past month, trading near $0.04, as broader interest in AI and experimental crypto projects continues to rise. The price activity reflects both renewed attention and the volatility that often follows dramatic developments in the space.
Yu’s final project intended as a philosophical and technical challenge to the speculative nature of memecoins has now become the subject of intense discussion, blending grief, innovation, and controversy in the rapidly evolving world of decentralized finance.
