The cryptocurrency universe has been teeming with surprising and noteworthy developments. These events are your chance to meet Jeffy Yu, the 22-year-old co-founder of the multi-national AI and blockchain project Zerebro. Yu was allegedly witnessed by thousands of people committing his suicide on a public livestream on May 4th, 2025. The video went viral across the Pump.fun platform, depicting Yu in an extremely agitated out-of-her-mind-on-video rage. Mixed messages and strange behavior have prompted hundreds of thousands to suspect that he faked his own death.
Compounding the befuddlement was an obituary for Yu that briefly appeared on Legacy.com before being taken down. The callous removal happened without notice or due cause from his family or law enforcement. This, coupled with Yu's scheduled release of Zerebro's AI album on May 30, raised suspicions about the legitimacy of his death.
Crypto Community Reacts with Skepticism
High-profile members of the cryptocurrency community have expressed doubt about Yu’s purported death. In response, crypto KOL Irene Zhao went on social media to say her own internal source had affirmed that Yu is indeed alive. Other prominent voices, such as Cobie, Ansem, and Hsaka, have raised skepticism, adding fuel to the fire and precipitating the drama.
"Faking your own death for a marketing stunt? That’s brutal, cold-blooded." - @Lu77okk
Compounding the confusion, local police and medical examiners have not issued any formal confirmation that Yu died. The lack of official statements has allowed speculation to run rampant, with many questioning the narrative presented in the livestream video. To this day, some viewers claim the video wasn’t even streamed live, but rather it was pre-recorded.
On-Chain Data Raises Questions
To add another layer of intrigue, on-chain data shows that key Yu’s wallet was still in use long after the livestream. This wallet, which is suspected of belonging to Yu’s, reportedly cashed out millions in $ZEREBRO tokens and moved the USDC into the HTX exchange. The money was then allegedly used to create a new token, $LLJEFFY.

The timing of $LLJEFFY’s launch was just about the same as Yu’s reported death, though. Within mere hours, the value of the token skyrocketed, achieving a market capitalization of $32.17 million. At inception, 70% of the token’s entire supply was burned to manufacture scarcity. The sudden increase in worth has raised eyebrows. There are people who think Yu might have planned the whole thing to freak out the market and short the token’s value on its way to the moon.
The Quest for Immortality on the Blockchain
Yu also wants to create a token that earns “immortality” on the blockchain. This cosmic vision extends beyond the death of humanity and enriches the philosophical underpinnings of the saga. Perhaps he felt the need to “sacrifice himself” so that $LLJEFFY could be made immortal. This idea is in line with the larger digital immortality narrative that’s taken off within crypto.
This notion of “sacrificing himself” in order to leave behind something eternal is a fascinating idea. Whether Yu actually planned to go through with committing suicide in real life or just symbolically through his project is the crux of the debate. This dangerously ambitious thrust makes things much more complex to an already confusing story about his supposed death.
