Zerebro founder Jeffy Yu reportedly suicides on livestream, after launching a ‘legacoin’

Unconfirmed reports are circulating online that Jeffy Yu, founder of the small-cap crypto project Zerebro, may have taken his own life during a livestream on Pump.fun on May 4. The video circulating on X appears to show Yu smoking a cigarette before shooting himself in the neck. While the footage has been widely shared, the authenticity of the video remains unconfirmed at this time. On the day of his alleged death, Yu published a philosophical and technical manifesto introducing the concept of Legacoins—a term he coined to represent a new category of memecoins rooted in permanence, legacy, and symbolic immortality. Yu defined Legacoins as: “An evolution of digital assets commonly referred to as memecoins... based on a voluntary commitment by the developers... to strictly acquire and never sell or trade these assets.” At its core, the Legacoin framework proposes that developers build and accumulate, never speculate or sell. Holdings become locked upon a holder’s death, thereby creating an immutable floor for the token’s price. “I am the permanent floor,” Yu wrote. Yu also launched the token LLJEFFY on the same day, which is apparently the first legacoin.

( Prev Acc Hacked ) (@buananarillaaa) May 6, 2025 Yu’s X account has since been deleted, but some in the community were skeptical. One user pointed out that Yu had previously stated a new Zerebro album would be released on May 30, and suggested the incident might be part of a planned marketing stunt. “Even if his X account is now deleted, don’t forget he told us the new Zerebro album is coming May 30. This fake suicide is just a part of the marketing. The ZEREBRO pump will be short and massive,” the post read. However, on May 6, the obituary platform Legacy published a notice stating that Jeffy Yu passed away on May 4 at the age of 22, seemingly confirming the reports of his death. Meanwhile, ZEREBRO token trades at around $0.04, up by 85% in the past month as it rides a broader wave of gains across the AI crypto sector.
