Bryan Johnson, the biotech entrepreneur and former Venmo CEO, has made a bold claim: he intends to be alive to witness Bitcoin’s last halving event in 2140. In a recent X post, Johnson stated, “Last Bitcoin halving is in 2140. I’m gonna be here for that — and make sure you are too.” This statement was accompanied by a promotional image for a conference where he is scheduled to speak in Las Vegas from May 27 to May 29.
Johnson’s confidence in his longevity stems from his extensive efforts to reverse his biological age using experimental regenerative techniques. According to Fortune, he spends millions annually on procedures such as red-light therapy, plasma infusions, and data-driven biometrics. As the lead investor and principal investigator in ‘Project Blueprint,’ Johnson aims to achieve an advanced state of longevity by evaluating numerous biomarkers and pushing the boundaries between biohacking and technology.
Johnson has garnered international attention for his relentless pursuit of slowing or reversing aging through self-experimentation and cutting-edge medical technologies. His methods include plasma transfusions and red light treatment, which have sparked both fascination and skepticism worldwide.
What is Bitcoin Halving?
Bitcoin halving is a programmed event in the cryptocurrency’s code that occurs approximately every four years. During this event, the reward for mining new Bitcoins is halved, reducing the total amount of Bitcoins mined over time. The process is designed to continue until the last bitcoin is mined around 2140, at which point the total supply will reach its hard cap of 21 million.

Johnson’s statement linking his longevity efforts to Bitcoin’s future has sparked interest across both the tech and cryptocurrency communities. While his anti-aging endeavors are controversial, they underscore the significant advancements being made in the field of regenerative medicine and longevity research.
